2MASX J00265906+6049388 Our marginal detection comes from the target. To check that we did not detect 2MASX J00265906+6049388 nearby 2MASX J00265869+6054037 (at 0.3b distance) instead, we directly 2MASX J00265906+6049388 observed the latter galaxy, which, at K^o= 12.2 mag, is not in the selected 2MASX J00265906+6049388 sample. It was not detected. 2MASX J00475430+6807433 There is a discrepancy between its HI and optical velocities. The velocity of 2MASX J00475430+6807433 our solid (SNR = 17) HI detection, 3763+/-5 km/s, is much higher than its 2MASX J00475430+6807433 reported optical velocity of 1273+/-65 km/s (Huchra et al., 2MASX J00475430+6807433 2012ApJS..199...26H). The galaxy is a late-type nearly edge-on spiral galaxy 2MASX J00475430+6807433 consistent with the HI profile parameters (i.e., W_50 = 341 km/s), and no 2MASX J00475430+6807433 other galaxy is visible within one beam radius distance. 2MASX J01281012+6313517 and J01281886+6302138: The profile of our marginal detection (V_HI=6040km/s) 2MASX J01281012+6313517 is lopsided and the lower velocity end uncertain. The baseline, however, is 2MASX J01281012+6313517 wavy and the profile could in fact extend to lower velocities (5750 km/s or 2MASX J01281012+6313517 even 5500 km/s). Since the target is a very edge-on spiral galaxy a line 2MASX J01281012+6313517 width larger than the one measured (W_50 = 154 km/s) seems likely. A low 2MASX J01281012+6313517 level confusion with 2MASX J01273787+6308155 at 2b, also detected by us 2MASX J01281012+6313517 (V_HI = 6223 km/s) cannot be excluded. Nearby 2MASX J01281886+6302138 2MASX J01281012+6313517 (at 1.0b) seems to show residuals of one or more detection as well but this 2MASX J01281012+6313517 is too uncertain to be listed as a detection. Slightly further away, at 1.4b, 2MASX J01281012+6313517 lies ZOAG G127.11+00.54 (not in the 2MASX catalogue) which has an optical 2MASX J01281012+6313517 velocity of 5639+/-44 km/s (Huchra et al. 1983=1983ApJS...52...89H). At 0.8b 2MASX J01281012+6313517 it lies closer to 2MASX J01281886+6302138, though, and would show up more 2MASX J01281012+6313517 prominently in this observation. 2MASX J01281886+6302138 and J01281012+6313517: The profile of our marginal detection (V_HI=6040km/s) 2MASX J01281886+6302138 is lopsided and the lower velocity end uncertain.

Nearby 2MASX J01281886+6302138 2MASX J01281886+6302138 (at 1.0b) seems to show residuals of one or more detection as well but this 2MASX J01281886+6302138 is too uncertain to be listed as a detection.

At 0.8b 2MASX J01281886+6302138 it lies closer to 2MASX J01281886+6302138, though, and would show up more 2MASX J01281886+6302138 prominently in this observation. 2MASX J01474890+6305128 Our detection is actually of a nearby, obscured galaxy, EZOA J0147+63. 2MASX J01474890+6305128 We observed this galaxy at a small offset of 0.1b (1.3') from its optical 2MASX J01474890+6305128 centre (i.e., at the position of 2MASX J01475111+6305278), but this should 2MASX J01474890+6305128 not affect its measured profile parameters. The blind Effelsberg EBHIS-ZoA 2MASX J01474890+6305128 HI survey (Schroeder et al. 2019b, 2019MNRAS.489.2907S) lists the same 2MASX J01474890+6305128 detection (EZOA J0147+63) but with a six times higher flux and an HI source 2MASX J01474890+6305128 position 2.4b away from our NRT target position, which means our detection is 2MASX J01474890+6305128 not of the NRT target. There is no visible counterpart for this 2MASX J01474890+6305128 EBHIS detection. 2MASX J02013241+6824219 Our central HI velocity of 3771+/-3 km/s is much lower than the only published 2MASX J02013241+6824219 optical measurement, 4554+/-55 km/s (Fisher et al. 1995ApJS..100...69F), 2MASX J02013241+6824219 which is, however, noted as a ``poor value''. To confirm whether our 2MASX J02013241+6824219 detection is correct, we also observed the galaxy 2MASX J02021731+6821460 at 2MASX J02013241+6824219 2.3b to the east of our target which has an optical velocity of 3675+/-42km/s 2MASX J02013241+6824219 (Strauss et al. 1992ApJS...83...29S) and two HI detections at 3577 km/s 2MASX J02013241+6824219 and 3578 km/s by Huchtmeier et al. 1995A&A...293L..33H (at Effelsberg) and 2MASX J02013241+6824219 Paturel et al. 2003A&A...412...57P (at the NRT), respectively. While 2MASX J02013241+6824219 comparing our NRT spectrum to the one by Paturel et al. is difficult, as due 2MASX J02013241+6824219 to our superimposed negative OFF-beam detection in the range ~3600-3700 km/s 2MASX J02013241+6824219 we only see HI emission in the range ~3700-3850 km/s, the Paturel et al. 2MASX J02013241+6824219 profile only goes up to ~3700 km/s. This means we have detected our target 2MASX J02013241+6824219 and not this nearby galaxy. 2MASX J02084091+7102087 and J02085980+7114029: The observation of 2MASX J02085980+7114029 2MASX J02084091+7102087 (V_HI = 2954 km/s, W_50 = 248 km/s) shows a clearly separated second 2MASX J02084091+7102087 detection in the beam at V_HI = 3304 km/s, which is of 2MASX J02084091+7102087 2MASX J02084091+7102087 at 1.1b distance (which was also observed directly by 2MASX J02084091+7102087 us) with an optical velocity of 3380+/-50 km/s 2MASX J02084091+7102087 (Nakanishi et al. 1997ApJS..112..245N). 2MASX J02085980+7114029 and J02084091+7102087: The observation of 2MASX J02085980+7114029 2MASX J02085980+7114029 (V_HI = 2954 km/s, W_50 = 248 km/s) shows a clearly separated second 2MASX J02085980+7114029 detection in the beam at V_HI = 3304 km/s, which is of 2MASX J02085980+7114029 2MASX J02084091+7102087 at 1.1b distance (which was also observed directly by 2MASX J02085980+7114029 us) with an optical velocity of 3380+/-50 km/s 2MASX J02085980+7114029 (Nakanishi et al. 1997ApJS..112..245N). 2MASX J02121002+6144326 Reported as detected with the NRAO 91m telescope by Kerr & Henning 2MASX J02121002+6144326 1987ApJ...320L..99K, but not detected by us. Given the 11' HPBW of that 2MASX J02121002+6144326 telescope, its reported position uncertainty is 5'-10', which means it could 2MASX J02121002+6144326 be the detection of a galaxy outside the NRT beam. Its reported total line 2MASX J02121002+6144326 flux is 3 K km/s, which we could not reduce to a reliable value in terms of 2MASX J02121002+6144326 Jy km/s, however. We compared the total line fluxes given in K km/s in their 2MASX J02121002+6144326 Table 3 for the seven detections identified with optical galaxies to their 2MASX J02121002+6144326 mean line fluxes given in Jy km/s in HyperLeda, but found too wide a range 2MASX J02121002+6144326 (1.0+/-0.9) of K/Jy conversion values. 2MASX J02531475+5528143 and J02531969+5529140 and Anon J025321.6+553602: Our HI spectrum of 2MASX J02531475+5528143 2MASX J02531969+5529140 shows two detections, centred on 3824 and 4462 km/s, 2MASX J02531475+5528143 respectively. The target does not have a published velocity. Well within the 2MASX J02531475+5528143 NRT beam, at 0.4b distance, lies the highly inclined galaxy 2MASX J02531475+5528143 2MASX J02531475+5528143, with a published uncertain optical velocity of 2MASX J02531475+5528143 4467+/-300 km/s (Lawrence et al. 1999MNRAS.308..897L), which matches 2MASX J02531475+5528143 the broader (W_50 = 121 km/s) of our two HI detections at 4462 km/s. 2MASX J02531475+5528143 Paturel et al. 2003A&A...412...57P obtained an NRT spectrum for this 2MASX J02531475+5528143 galaxy with a detection at V_HI = 3834 km/s (W_50 = 78 km/s and peak 2MASX J02531475+5528143 S_p = 60 mJy) but did not detect our 4462 km/s profile (their rms is higher). 2MASX J02531475+5528143 In addition, we observed a fainter spiral galaxy visible on DSS images to the 2MASX J02531475+5528143 north at 0.5b distance (Anon J025321.6+553602) which is not in the 2MASX J02531475+5528143 2MASX catalogue and again detected both profiles, at 3826 and 4351 km/s, 2MASX J02531475+5528143 respectively. For the narrower profile at V_HI = 3824 km/s (W_50 = 63 km/s) 2MASX J02531475+5528143 our flux towards 2MASX J02531969+5529140 is F_HI = 4.9 Jy km/s , slightly 2MASX J02531475+5528143 lower for Anon J025321.6+553602: F_HI = 4.3 Jy km/s and lowest for 2MASX J02531475+5528143 2MASX J02531475+5528143: F_HI = 3.3 Jy km/s. The blind Effelsberg EBHIS-ZoA 2MASX J02531475+5528143 survey (Schroeder et al. 2019b, 2019MNRAS.489.2907S), however, lists the same 2MASX J02531475+5528143 detection (EZOA J0253+55) with a total flux twice as high as ours 2MASX J02531475+5528143 (F_HI = 9.7 Jy km/s) but at a position outside of our beams 2MASX J02531475+5528143 (RA,Dec = 02:53:37.0,+55:25:19, with a positional uncertainty of about 1.2') 2MASX J02531475+5528143 They identified an uncatalogued galaxy visible on the DSS located ~1b away 2MASX J02531475+5528143 from both our target positions as the counterpart (at 2MASX J02531475+5528143 RA,Dec =02:53:32.4,+55:27:16). The broader profile seems to be confused. 2MASX J02531475+5528143 It was detected at 4462 km/s (W_20 = 419 km/s) in the 2MASX J02531969+5529140 2MASX J02531475+5528143 pointing, at 4351 km/s (W_20 = 424 km/s) in the Anon galaxy pointing and at 2MASX J02531475+5528143 4337 km/s (W_20 = 387 km/s) in the 2MASX J02531475+5528143 pointing. All 2MASX J02531475+5528143 three galaxies seem to contribute though it is not possible to distentangle 2MASX J02531475+5528143 the contributions. Based on the the various peak fluxes and the morphologies 2MASX J02531475+5528143 of the galaxies, we can estimate that the peak at 4200 km/s comes from 2MASX J02531475+5528143 2MASX J02531475+5528143 and possibly goes up to 4500 km/s since the galaxy is 2MASX J02531475+5528143 nearly edge-on. The emission in the 4400-4500 km/s range is most pronounced 2MASX J02531475+5528143 at the 2MASX J02531969+5529140 pointing and would match with the more 2MASX J02531475+5528143 face-on appearance of this galaxy. The Anon galaxy pointing seems to show 2MASX J02531475+5528143 more emission than based on the distance to the other targets (0.5b and 0.8b) 2MASX J02531475+5528143 and the only identifiable peak that is more promnent than in the 2MASX J02531475+5528143 other pointings is at 4300 km/s. 2MASX J02531969+5529140 and J02531475+5528143 and Anon J025321.6+553602: Our HI spectrum of 2MASX J02531969+5529140 2MASX J02531969+5529140 shows two detections, centred on 3824 and 4462 km/s, 2MASX J02531969+5529140 respectively.

The blind Effelsberg EBHIS-ZoA Anon J025321.6+553602 survey (Schroeder et al. 2019b, 2019MNRAS.489.2907S), however, lists the same Anon J025321.6+553602 detection (EZOA J0253+55) with a total flux twice as high as ours Anon J025321.6+553602 (F_HI = 9.7 Jy km/s) but at a position outside of our beams Anon J025321.6+553602 (RA,Dec = 02:53:37.0,+55:25:19, with a positional uncertainty of about 1.2') Anon J025321.6+553602 They identified an uncatalogued galaxy visible on the DSS located ~1b away Anon J025321.6+553602 from both our target positions as the counterpart (at Anon J025321.6+553602 RA,Dec =02:53:32.4,+55:27:16). The broader profile seems to be confused. Anon J025321.6+553602 It was detected at 4462 km/s (W_20 = 419 km/s) in the 2MASX J02531969+5529140 Anon J025321.6+553602 pointing, at 4351 km/s (W_20 = 424 km/s) in the Anon galaxy pointing and at Anon J025321.6+553602 4337 km/s (W_20 = 387 km/s) in the 2MASX J02531475+5528143 pointing. All Anon J025321.6+553602 three galaxies seem to contribute though it is not possible to distentangle Anon J025321.6+553602 the contributions. Based on the the various peak fluxes and the morphologies Anon J025321.6+553602 of the galaxies, we can estimate that the peak at 4200 km/s comes from Anon J025321.6+553602 2MASX J02531475+5528143 and possibly goes up to 4500 km/s since the galaxy is Anon J025321.6+553602 nearly edge-on. The emission in the 4400-4500 km/s range is most pronounced Anon J025321.6+553602 at the 2MASX J02531969+5529140 pointing and would match with the more Anon J025321.6+553602 face-on appearance of this galaxy. The Anon galaxy pointing seems to show Anon J025321.6+553602 more emission than based on the distance to the other targets (0.5b and 0.8b) Anon J025321.6+553602 and the only identifiable peak that is more promnent than in the Anon J025321.6+553602 other pointings is at 4300 km/s. 2MASX J03104409+6106477 and J03111176+6105047: Our HI spectrum taken towards 2MASX J03111176+6105047 2MASX J03104409+6106477 shows a clear detection at 2775 km/s and a possible at 2568 km/s. The galaxy 2MASX J03104409+6106477 has no optical velocity. At a distance of 1.9b lies another of our HI 2MASX J03104409+6106477 targets, 2MASX J03104409+6106477, with a tentative detection at 2505 km/s. 2MASX J03104409+6106477 It is possibly interacting with a companion, 2MASX J03105210+6107066 (which 2MASX J03104409+6106477 is an IRAS source), at 1.0' distance (and 0.6b from the first target 2MASX J03104409+6106477 2MASX J03111176+6105047). The brighter of the two, 2MASX J03104409+6106477, 2MASX J03104409+6106477 has an optical velocity of 2350+/-60 km/s in the CfA velocity catalog 2MASX J03104409+6106477 (Huchra et al. 1995ApJS...99..391H) but it may not be reliable as it 2MASX J03104409+6106477 does not appear in the 2MRS Extra Catalog 2MASX J03104409+6106477 (Huchra et al. 2012ApJS..199...26H). There are no sufficient data to 2MASX J03104409+6106477 conclude that 2MASX J03104409+6106477 has been detected. 2MASX J03111176+6105047 and J03104409+6106477: Our HI spectrum taken towards 2MASX J03111176+6105047 2MASX J03111176+6105047 shows a clear detection at 2775 km/s and a possible at 2568 km/s. The galaxy 2MASX J03111176+6105047 has no optical velocity.

There are no sufficient data to 2MASX J03111176+6105047 conclude that 2MASX J03104409+6106477 has been detected. 2MASX J03202205+6645055 and Anon J031958.7+664959: Our detection at V_HI = 2993 km/s for 2MASX J03202205+6645055 2MASX J03202205+6645055 is actually of HIJASS J0319+66 (Lang et al. 2MASX J03202205+6645055 2003yCat..73420738L) at V_HI = 3005 km/s which has a higher peak flux 2MASX J03202205+6645055 density. The optical counterpart of the detection is Anon J031958.7+664959 at 2MASX J03202205+6645055 1.3b distance. We have confirmed this with a separate observation of 2MASX J03202205+6645055 Anon J031958.7+664959. Anon J031958.7+664959 and 2MASX J03202205+6645055: Our detection at V_HI = 2993 km/s for Anon J031958.7+664959 2MASX J03202205+6645055 is actually of HIJASS J0319+66 (Lang et al. Anon J031958.7+664959 2003yCat..73420738L) at V_HI = 3005 km/s which has a higher peak flux Anon J031958.7+664959 density. The optical counterpart of the detection is Anon J031958.7+664959 at Anon J031958.7+664959 1.3b distance. We have confirmed this with a separate observation of Anon J031958.7+664959 Anon J031958.7+664959. 2MASX J03292042+6601389 Our central HI velocity of 2113+/-7 km/s is 69 km/s (4 sigma) lower than the 2MASX J03292042+6601389 published optical velocity of 2182+/-14 km/s 2MASX J03292042+6601389 (Huchra et al. 2012ApJS..199...26H). The target is a large and inclined 2MASX J03292042+6601389 medium type spiral, also detected by IRAS, and thus we would expect to 2MASX J03292042+6601389 detect it easily. No other candidate is visible within the beam radius and 2MASX J03292042+6601389 we conclude that we detected the target. 2MASX J03393937+6527116 and J03394709+6528486: Their HI profiles are mutually confused. Observations 2MASX J03393937+6527116 were made towards each of the galaxies in this pair with 0.5b N-S separation 2MASX J03393937+6527116 They have similar optical velocities (Huchra et al. 2012ApJS..199...26H), the 2MASX J03393937+6527116 former at 5177+/-37 km/s and the latter at 5222+/-70 km/s. Comparing the two 2MASX J03393937+6527116 HI profiles, it appears that the higher velocity peak, at ~5300 km/s, is most 2MASX J03393937+6527116 likely due to 2MASX J03394709+6528486 (which is the lesser inclined), but 2MASX J03393937+6527116 due to their proximity their HI profiles cannot be disentangled. 2MASX 03394709+65284866 and J03393937+6527116: Their HI profiles are mutually confused. Observations 2MASX 03394709+65284866 were made towards each of the galaxies in this pair with 0.5b N-S separation 2MASX 03394709+65284866 They have similar optical velocities (Huchra et al. 2012ApJS..199...26H), the 2MASX 03394709+65284866 former at 5177+/-37 km/s and the latter at 5222+/-70 km/s.

The optical velocity of the 2MASX J03403139+6649043 target, 5008+/-52 km/s (Huchra et al. 2012ApJS..199...26H) does not agree 2MASX J03403139+6649043 with our HI velocity of 1574 km/s. 2MASX J03400768+6642470 (at 1.4b to the 2MASX J03403139+6649043 SW) is a large inclined spiral and a more likely candidate for our HI 2MASX J03403139+6649043 detection, as it has a published NRT HI velocity of 1496 km/s (Paturel et al. 2MASX J03403139+6649043 2003A&A...412...57P). Our detection shows only the high-velocity horn of 2MASX J03403139+6649043 their profile. 2MASX J03480684+4955450 and J03480963+4955140 and J03482002+4955207: There are three galaxies close 2MASX J03480684+4955450 together which we all observed in turn: 2MASX J03480684+4955450 and 2MASX J03480684+4955450 2MASX J03482002+4955207 are at 0.2b and 0.9b from 2MASX J03480963+4955140, 2MASX J03480684+4955450 respectively. All three pointings show a detection at V_HI ~ 10,000 km/s, 2MASX J03480684+4955450 but in the case of 2MASX J03482002+4955207 it is fainter, consistent with the 2MASX J03480684+4955450 detection being either of 2MASX J03480963+4955140 or of 2MASX J03480684+4955450 2MASX J03480684+4955450. The latter two are too close together for such a 2MASX J03480684+4955450 comparison, and it is likely (based on the form of the profiles) that both 2MASX J03480684+4955450 contribute to the HI detection: both are medium-type spirals, with 2MASX J03480684+4955450 2MASX J03480684+4955450 less inclined than 2MASX J03480963+4955140, which has 2MASX J03480684+4955450 an optical velocity of 9684 km/s without listed uncertainty 2MASX J03480684+4955450 (Nakanishi et al. 1997ApJS..112..245N). 2MASX J03480963+4955140 and J03480684+4955450 and J03482002+4955207: There are three galaxies close 2MASX J03480963+4955140 together which we all observed in turn: 2MASX J03480684+4955450 and 2MASX J03480963+4955140 2MASX J03482002+4955207 are at 0.2b and 0.9b from 2MASX J03480963+4955140, 2MASX J03480963+4955140 respectively.

There is also some additional 2MASX J04002219+3839233 emission at the high-velocity end (<= 6700 km/s), which is likely due to 2MASX J04002219+3839233 another galaxy in the vicinity. We have also observed the bright 2MASX J04002219+3839233 (K^o = 9.4mag) 2MASX J04002709+3854173 at 1.4b to the north, which has an 2MASX J04002219+3839233 optival velocity of 6134+/-58 km/s (Huchra et al. 2012ApJS..199...26H) but 2MASX J04002219+3839233 it is not detected. There are smaller galaxies in the region, one of which 2MASX J04002219+3839233 may be contributing to the signal. 2MASX J04002709+3854173 and J04002219+3839233: 2MASX J04002219+3839233 is a very edge-on large spiral, 2MASX J04002709+3854173 and the detection shows a nice double horn.

We have also observed the bright 2MASX J04002709+3854173 (K^o = 9.4mag) 2MASX J04002709+3854173 at 1.4b to the north, which has an 2MASX J04002709+3854173 optival velocity of 6134+/-58 km/s (Huchra et al. 2012ApJS..199...26H) but 2MASX J04002709+3854173 it is not detected. There are smaller galaxies in the region, one of which 2MASX J04002709+3854173 may be contributing to the signal. 2MASX J04114143+3841285 Our detection appears to be of another galaxy. The target has an optical 2MASX J04114143+3841285 velocity of 6438+/-63 km/s (Huchra et al. 2012ApJS..199...26H) and is likely 2MASX J04114143+3841285 an elliptical or S0 galaxy. Our HI detection at 5698 km/s appears to be of 2MASX J04114143+3841285 nearby (1.1b to the north) 2MASX J04113202+3846565, which has an NRT HI 2MASX J04114143+3841285 detection (Paturel et al. 2003A&A...412...57P) at 5724 km/s. Their peak flux 2MASX J04114143+3841285 density is about twice as high as ours. 2MASX J04115755+3838463 and J04115864+3842213, J04120068+3846073 and J04121283+3842023: The first 2MASX J04115755+3838463 three galaxies lie within the same NRT beam, and the separations between this 2MASX J04115755+3838463 N-S oriented trio are 0.4b and 0.3b (counted from N to S). To the east at 2MASX J04115755+3838463 1.5b distance lies 2MASX J04121283+3842023 (while to the west at 1.1b is 2MASX J04115755+3838463 2MASX J04114143+3841285 which we discussed above). In all four spectra broad 2MASX J04115755+3838463 (W_50 ~ 500 km/s) HI emission is detected around V_HI ~ 5770 km/s, with 2MASX J04115755+3838463 F_HI ~ 4.9-6.7 Jy km/s. This is not consistent with the optical velocities 2MASX J04115755+3838463 (Huchra et al. 2012ApJS..199...26H) for 2MASX J04115755+3838463 2MASX J04115755+3838463 (7008+/-58 km/s) and for 2MASX J04115864+3842213 (6535+/-69 km/s). 2MASX J04115755+3838463 These four galaxies, together with several more of our targets (e.g., 2MASX J04115755+3838463 2MASX J04122913+3838553) seem to be part of the galaxy group HCDE 0271 with 2MASX J04115755+3838463 a mean velocity of 6491 km/s (Crook et al. 2007ApJ...655..790C). 2MASX J04115755+3838463 Interestingly, five of the six published optical velocities (Huchra et al. 2MASX J04115755+3838463 2012ApJS..199...26H) in the area are indeed >10 sigma higher than the 2MASX J04115755+3838463 HI detections of our quadruple. On the other hand, one galaxy in the 2MASX J04115755+3838463 outskirts of the group, 2MASXJ04131853+3819491, was detected by us at a 2MASX J04115755+3838463 similar velocity as published (V_HI = 6441 km/s vs. V_opt = 6482 km/s). 2MASX J04115755+3838463 While 2MASX J04121283+3842023 to the east of the N-S trio (1.5b from 2MASX J04115755+3838463 2MASX J04115864+3842213) as well as 2MASX J04120068+3846073 (both without 2MASX J04115755+3838463 optical velocity) show the strongest emission in the 5700-5850 km/s range 2MASX J04115755+3838463 (S_p ~ 14 mJy), 2MASX J04121283+3842023 does not show the strong peak at 2MASX J04115755+3838463 ~6000 km/s that is found in all the other spectra. Considering the line 2MASX J04115755+3838463 fluxes, we find that 2MASX J04120068+3846073 to the north shows the highest 2MASX J04115755+3838463 flux (F_HI = 6.7 Jy km/s), J04115864+3842213 (in the centre) has the lowest 2MASX J04115755+3838463 (4.9 Jy km/s) and the other two have ~5.4 Jy km/s. We conclude that 2MASX J04115755+3838463 2MASX J04120068+3846073 and J04121283+3842023 are definitely detected, and 2MASX J04115755+3838463 J04115755+3838463 very likely (despite its high optical velocity). We cannot 2MASX J04115755+3838463 say much about J04115864+3842213 in the centre though: most of the flux 2MASX J04115755+3838463 observed towards it is likely due to the surrounding galaxies. Though the 2MASX J04115755+3838463 extinction is high in this area (A_K ~ 0.5 mag), we have deep UKIDSS images 2MASX J04115755+3838463 that show even the fainter spiral discs and arms. There is no hidden galaxy 2MASX J04115755+3838463 that could account for (parts of) the HI detection (in particular of 2MASX J04115755+3838463 J04115755+3838463), only one diffuse galaxy is visible at about 1b from both 2MASX J04115755+3838463 2MASX J04115864+3842213 and J04121283+3842023 (RA,Dec =04:12:05.7,+38:47:52) 2MASX J04115755+3838463 but it is too small to be a likely contributor. 2MASX J04115864+3842213 and J04115755+3838463, J04120068+3846073 and J04121283+3842023: The first 2MASX J04115864+3842213 three galaxies lie within the same NRT beam, and the separations between this 2MASX J04115864+3842213 N-S oriented trio are 0.4b and 0.3b (counted from N to S). To the east at 2MASX J04115864+3842213 1.5b distance lies 2MASX J04121283+3842023 (while to the west at 1.1b is 2MASX J04115864+3842213 2MASX J04114143+3841285 which we discussed above).

The third target, 2MASX J04124119+3843433 2MASX J04122913+3838553 at 1.4b from J04124119+3843433, shows tentatively the 2MASX J04124119+3843433 same peak but is heavily affected by the OFF-beam detection of 2MASX J04124119+3843433 2MASX J04131853+3819491 in the range 6300-6600 km/s (spectrum not shown) 2MASX J04124119+3843433 We conclude that all three observations detected the same object, namely 2MASX J04124119+3843433 2MASX J04124119+3843433. All three targets are likely part of the HCDE 0271 2MASX J04124119+3843433 group discussed above. 2MASX J04124692+3835153 and J04122913+3838553 and J04124119+3843433: All three observations appear to 2MASX J04124692+3835153 have detected the same object, 2MASX J04124119+3843433.

All three targets are likely part of the HCDE 0271 2MASX J04124692+3835153 group discussed above. 2MASX J04240288+3731070 and J04241490+3725180 and J04242347+3724490: All three detections are of the 2MASX J04240288+3731070 same object, 2MASX J04241490+3725180 (at V_HI ~ 6800 km/s). 2MASX J04240288+3731070 Both 2MASX J04240288+3731070 and J04242347+3724490 have much lower optical 2MASX J04240288+3731070 velocities of 5969+/-70 km/s and 6259+/-47 km/s, respectively (Huchra et al. 2MASX J04240288+3731070 2012ApJS..199...26H). They are separated by 1.4b and 1.0b, respectively, 2MASX J04240288+3731070 from J04241490+3725180 which agrees with their respective flux ratios of 34% 2MASX J04240288+3731070 and 68% as compared to 2MASX J04241490+3725180 (F_HI = 1.32 Jy km/s). 2MASX J04241490+3725180 and J04240288+3731070 and J04242347+3724490: All three detections are of the 2MASX J04241490+3725180 same object, 2MASX J04241490+3725180 (at V_HI ~ 6800 km/s). 2MASX J04241490+3725180 Both 2MASX J04240288+3731070 and J04242347+3724490 have much lower optical 2MASX J04241490+3725180 velocities of 5969+/-70 km/s and 6259+/-47 km/s, respectively (Huchra et al. 2MASX J04241490+3725180 2012ApJS..199...26H).

The extinction in this area is fairly 2MASX J04341003+2556378 high at A_B = 6.1 mag and no other galaxy is visible within two beam radii. 2MASX J04341003+2556378 It is not clear whether the strong single peak emission at V_HI ~ 7200 km/s 2MASX J04341003+2556378 comes from a disturbed HI disc (the galaxy has a NIR inclination of 56 deg) 2MASX J04341003+2556378 or from an invisible companion. 2MASX J04481569+3435012 and J04481997+3436502: 2MASX J04481997+3436502 has an optical velocity of 2MASX J04481569+3435012 6453+/-72 km/s (Huchra et al. 2012ApJS..199...26H), which is ~5 sigma higher 2MASX J04481569+3435012 than our HI velocity of 6125+/-6 km/s; it is a rather narrow profile 2MASX J04481569+3435012 (W_50 = 76 km/s). There is another galaxy in the beam, 2MASX J04481569+3435012 2MASX J04481569+3435012 at 0.5b distance, which has a later morphological 2MASX J04481569+3435012 type and a similar appearance on WISE NIR images as our target (but is, at 2MASX J04481569+3435012 K^o = 12.5 mag, too faint for our sample). Our marginal HI profile of 2MASX J04481569+3435012 2MASX J04481569+3435012 (see Spectrum) shows the same detection as well as 2MASX J04481569+3435012 fainter emission next to it. Altogether the peak flux in this observation is 2MASX J04481569+3435012 comparable to that of 2MASX J04481997+3436502, which means, assuming some 2MASX J04481569+3435012 contribution from the underlying broader profile, that the narrow and strong 2MASX J04481569+3435012 profile is indeed due to 2MASX J04481997+3436502. 2MASX J04481997+3436502 and J04481569+3435012: 2MASX J04481997+3436502 has an optical velocity of 2MASX J04481997+3436502 6453+/-72 km/s (Huchra et al. 2012ApJS..199...26H), which is ~5 sigma higher 2MASX J04481997+3436502 than our HI velocity of 6125+/-6 km/s; it is a rather narrow profile 2MASX J04481997+3436502 (W_50 = 76 km/s).

The pointing towards 2MASX J04580771+3533503 2MASX J04580945+3523013 shows another galaxy in the beam at 0.9b distance 2MASX J04580771+3533503 which is not in our sample (2MASX J04580771+3533503 with K^o = 11.6 mag) 2MASX J04580771+3533503 We also observed this object directly and find that its flux is about twice 2MASX J04580771+3533503 as high as for 2MASX J04580945+3523013. 2MASX J04580945+3523013 and J04580771+3533503: Only the former was detected. The pointing towards 2MASX J04580945+3523013 2MASX J04580945+3523013 shows another galaxy in the beam at 0.9b distance 2MASX J04580945+3523013 which is not in our sample (2MASX J04580771+3533503 with K^o = 11.6 mag) 2MASX J04580945+3523013 We also observed this object directly and find that its flux is about twice 2MASX J04580945+3523013 as high as for 2MASX J04580945+3523013. 2MASX J05014040+4338109 Two discrepant HI velocities have been reported for this galaxy, 5161+/-7km/s 2MASX J05014040+4338109 (Hauschildt 1987A&A...184...43H) at Effelsberg and ~7170 km/s (Haynes et al. 2MASX J05014040+4338109 1988AJ.....95..607H, Springob et al. 2005ApJS..160..149S) at the NRAO 300-ft. 2MASX J05014040+4338109 The former, rather weak (F_HI = 1.3+/-0.9 Jy km/s) detection appears to be 2MASX J05014040+4338109 affected by a baseline ripple. Our detection at 7194 km/s is consistent with 2MASX J05014040+4338109 the latter. 2MASX J05200866+4314313 Our detection at V_HI = 3785+/-2 km/s appears to be of the target. Nearby (at 2MASX J05200866+4314313 0.6b distance) 2MASX J05201415+4318214 has an uncertain optical velocity of 2MASX J05200866+4314313 3600+/-600 km/s (Hill et al. 1988AJ.....95.1031H) and a published NRT HI 2MASX J05200866+4314313 velocity of 3767+/-4 km/s (Martin et al. 1990A&A...235...41M). The published 2MASX J05200866+4314313 NRT profile is lopsided, while ours appears level and broader (W_20 of 172 2MASX J05200866+4314313 vs. 147 km/s). We therefore assume that our target 2MASX J05200866+4314313 is 2MASX J05200866+4314313 the detected galaxy in both cases (it seems likely that 2MASX J05200866+4314313 2MASX J05201415+4318214 appears in the published profile as a low-velocity 2MASX J05200866+4314313 shoulder). 2MASX J05515780+1807051 Our target is the most likely counterpart, although there are two other 2MASX J05515780+1807051 possible candidates for the HI detection: there is a faint edge-on spiral 2MASX J05515780+1807051 visible on the DSS at 0.6b distance, and a 2MASS galaxy (at K^o = 12.2 mag it 2MASX J05515780+1807051 is not in our sample) at 0.5b, both only slightly smaller than the target. 2MASX J05515780+1807051 None have optical velocities. 2MASX J05583605+4031118 Our target was not detected. It is a close pair with 2MASX J05583132+4031028 2MASX J05583605+4031118 (at 0.5b), which we have also observed (to be published in the forthcoming 2MASX J05583605+4031118 paper on the TF relation). Since both the flux and the peak flux are about 2MASX J05583605+4031118 0.8 times lower for our target 2MASX J05583605+4031118, we concluded that the 2MASX J05583605+4031118 detection made towards our target is due to its close neighbour. 2MASX J05585447+1759445 and J05590035+1806455 and J05590393+1804285: We detected similar HI profiles 2MASX J05585447+1759445 around 6000 km/s towards all three targets, none of which have optical 2MASX J05585447+1759445 velocities. Together with another of our targets (2MASX J05583483+1754200), 2MASX J05585447+1759445 which has a clearly separate profile at 6092 km/s, they seem to form a small 2MASX J05585447+1759445 group. A fifth galaxy, a late type spiral only visible on the deep UKIDSS 2MASX J05585447+1759445 images (RA,Dec = 05:58:49.2,+17:58:57) at 0.7b distance from 2MASX J05585447+1759445 2MASX J05585447+1759445 is also a possible member. 2MASX J05590035+1806455 2MASX J05585447+1759445 and J05590393+1804285 show similar fluxes (F_HI ~ 2.7 Jy km/s) and the 2MASX J05585447+1759445 contributions of the individual galaxies cannot be disentangled due to their 2MASX J05585447+1759445 proximity (at 0.5b or 2.4' to the north). We detected a similar HI profile 2MASX J05585447+1759445 towards 2MASX J05585447+1759445, but with about half the integrated line flux 2MASX J05585447+1759445 -- this can be explained entirely by the detection of the other two galaxies, 2MASX J05585447+1759445 given their projected distances (1.0b and 1.3b, respectively), without the 2MASX J05585447+1759445 need for additional emission from 2MASX J05585447+1759445. The prominent peak 2MASX J05585447+1759445 at ~5900 km/s visible in the observation of both J05585447+1759445 and 2MASX J05585447+1759445 J05590035+1806455 but less in J05590393+1804285 could possibly come from the 2MASX J05585447+1759445 unknown galaxy mentioned above. 2MASX J05590035+1806455 and J05585447+1759445 and J05590393+1804285: We detected similar HI profiles 2MASX J05590035+1806455 around 6000 km/s towards all three targets, none of which have optical 2MASX J05590035+1806455 velocities.

A fifth galaxy, a late type spiral only visible on the deep UKIDSS 2MASX J05590393+1804285 images (RA,Dec = 05:58:49.2,+17:58:57) at 0.7b distance from 2MASX J05590393+1804285 2MASX J05585447+1759445 is also a possible member. 2MASX J05590035+1806455 2MASX J05590393+1804285 and J05590393+1804285 show similar fluxes (F_HI ~ 2.7 Jy km/s) and the 2MASX J05590393+1804285 contributions of the individual galaxies cannot be disentangled due to their 2MASX J05590393+1804285 proximity (at 0.5b or 2.4' to the north). We detected a similar HI profile 2MASX J05590393+1804285 towards 2MASX J05585447+1759445, but with about half the integrated line flux 2MASX J05590393+1804285 -- this can be explained entirely by the detection of the other two galaxies, 2MASX J05590393+1804285 given their projected distances (1.0b and 1.3b, respectively), without the 2MASX J05590393+1804285 need for additional emission from 2MASX J05585447+1759445. The prominent peak 2MASX J05590393+1804285 at ~5900 km/s visible in the observation of both J05585447+1759445 and 2MASX J05590393+1804285 J05590035+1806455 but less in J05590393+1804285 could possibly come from the 2MASX J05590393+1804285 unknown galaxy mentioned above. 2MASX J06074379+1608036 and J06074754+1604526: 2MASX J06074754+1604526 shows a profile similar to 2MASX J06074379+1608036 2MASX J06074379+1608036 but with a 24% lower flux (their separation is 0.5b). 2MASX J06074379+1608036 The profile of 2MASX J06074379+1608036 looks confused, and its Effelsberg 2MASX J06074379+1608036 EBHIS-ZoA detection by Schroeder et al. 2019b, 2019MNRAS.489.2907S 2MASX J06074379+1608036 (EZOA J0607+16; F_HI = 5.9 Jy km/s) shows the peak at V_HI = 5650 km/s more 2MASX J06074379+1608036 clearly. They list both 2MASX J06074379+1608036 and an LSB galaxy at 2MASX J06074379+1608036 (RA,Dec = 06:07:34.5,+16:06:03) as the counterparts of the EZOA source. 2MASX J06074379+1608036 We conclude that we did not detect 2MASX J06074754+1604526, and that our 2MASX J06074379+1608036 profile of 2MASX J06074379+1608036 shows at the high velocity end 2MASX J06074379+1608036 contamination by the aforementioned LSB galaxy at 1.2b distance 2MASX J06074379+1608036 (or 1.7b from 2MASX J06074754+1604526). 2MASX J06074754+1604526 and J06074379+1608036: 2MASX J06074754+1604526 shows a profile similar to 2MASX J06074754+1604526 2MASX J06074379+1608036 but with a 24% lower flux (their separation is 0.5b). 2MASX J06074754+1604526 The profile of 2MASX J06074379+1608036 looks confused, and its Effelsberg 2MASX J06074754+1604526 EBHIS-ZoA detection by Schroeder et al. 2019b, 2019MNRAS.489.2907S 2MASX J06074754+1604526 (EZOA J0607+16; F_HI = 5.9 Jy km/s) shows the peak at V_HI = 5650 km/s more 2MASX J06074754+1604526 clearly. They list both 2MASX J06074379+1608036 and an LSB galaxy at 2MASX J06074754+1604526 (RA,Dec = 06:07:34.5,+16:06:03) as the counterparts of the EZOA source. 2MASX J06074754+1604526 We conclude that we did not detect 2MASX J06074754+1604526, and that our 2MASX J06074754+1604526 profile of 2MASX J06074379+1608036 shows at the high velocity end 2MASX J06074754+1604526 contamination by the aforementioned LSB galaxy at 1.2b distance 2MASX J06074754+1604526 (or 1.7b from 2MASX J06074754+1604526). 2MASX J06100449+2029063 The spectrum of this pointing shows a barely resolved (W_50 = 27 km/s, at 2MASX J06100449+2029063 18 km/s resolution) non-RFI spike at 4521 km/s, very similar to the one found 2MASX J06100449+2029063 in the spectra of 2MASX J20194861+4046363 and J20201209+4039396 2MASX J06100449+2029063 (at 4470 km/s). Though the extinction is very high (A_K = 3.5 mag) the UKIDSS 2MASX J06100449+2029063 image shows large, open spiral arms indicating a nearly face-on late-type 2MASX J06100449+2029063 spiral. To check on this detection, we obtained a test observation at 2.0b 2MASX J06100449+2029063 distance where we found the same spike with lower flux; however, the flux 2MASX J06100449+2029063 ratio of 0.7 does not agree with the large distance between the two pointings 2MASX J06100449+2029063 and the target is listed as not detected. 2MASX J06171616+1655575 We detected a complex, broad (W_50 = 552 km/s) profile towards this target, 2MASX J06171616+1655575 which is not due to RFI or baseline curvature. The target is an inclined 2MASX J06171616+1655575 spiral, though far from being edge-on, and thus is unlikely to account 2MASX J06171616+1655575 entirely for such a broad profile. At 0.9b due south is an inclined medium 2MASX J06171616+1655575 type spiral 2MASX J06171664+1645515 (at K^o = 11.5 mag it is not in our 2MASX J06171616+1655575 sample) that might give rise to confusion within the beam, though at 2MASX J06171616+1655575 A_K = 0.5 mag the presence of another hidden late-type galaxy in the 2MASX J06171616+1655575 telescope beam cannot be excluded. 2MASX J06354846+1115047 Our profile (V_HI = 3838 km/s) is confused with emission from 2MASX J06354846+1115047 ADBS J063549+1107, at 0.6b (or 7.4') distance, for which Rosenberg et al. 2MASX J06354846+1115047 2000ApJS..130..177R measured V_HI = 3765 km/s at Arecibo (W_50 = 389 km/s , 2MASX J06354846+1115047 F_HI = 5.3 Jy km/s). A near-by (0.2b) HIPASS detection (HIPASS J0635+11) at 2MASX J06354846+1115047 V_HI = 3575 km/s is likely to be associated with another detection by 2MASX J06354846+1115047 Rosenberg et al. 2000ApJS..130..177R at V_HI = 3570 km/s, ADBS J063603+1109, 2MASX J06354846+1115047 which lies outside our beam at 2.0b. 2MASX J06455492-1812493 =NGC 2283: We seem to have underestimated the HI line flux of this extended 2MASX J06455492-1812493 object. While NGC 2283 is listed in the 2MASS Large Galaxy Atlas (Jarrett et 2MASX J06455492-1812493 al. 2003AJ....125..525J), its position listed in the Extended Source 2MASX J06455492-1812493 catalogue is that of a star in the outer parts. The observed position 2MASX J06455492-1812493 therefore lies 35'' W (0.3b) of the galaxy centre, which should not really 2MASX J06455492-1812493 affect the HI detection for a source smaller than the telescope beam. 2MASX J06455492-1812493 However, our line flux is 72 Jy km/s compared to 119 Jy km/s measured by 2MASX J06455492-1812493 HIPASS (Doyle et al. 2005MNRAS.361...34D) and 101 Jy km/s measured with the 2MASX J06455492-1812493 Effelsberg radio telescope (Huchtmeier & Richter 1986A&AS...63..323H), With 2MASX J06455492-1812493 an optical diameter of 3.6' it is likely that the (presumably larger) HI 2MASX J06455492-1812493 disc of the galaxy is larger than the NRT E-W beam size. 2MASX J06590153+0634579 and Anon J065845.2+063640: There is a late-type anonymous spiral visible on 2MASX J06590153+0634579 the blue DSS image at 2.2b distance (RA,Dec = 06:58:45.2,06:36:40) from our 2MASX J06590153+0634579 2MASX target. We also observed this galaxy directly as a check for the 2MASX J06590153+0634579 lopsided profile and detected it marginally at ~300 km/s higher velocity 2MASX J06590153+0634579 (and clearly separated from the former profile) which means the two galaxies 2MASX J06590153+0634579 are both detected and form a pair. Anon J065845.2+063640 and 2MASX J06590153+0634579: There is a late-type anonymous spiral visible on Anon J065845.2+063640 the blue DSS image at 2.2b distance (RA,Dec = 06:58:45.2,06:36:40) from our Anon J065845.2+063640 2MASX target. We also observed this galaxy directly as a check for the Anon J065845.2+063640 lopsided profile and detected it marginally at ~300 km/s higher velocity Anon J065845.2+063640 (and clearly separated from the former profile) which means the two galaxies Anon J065845.2+063640 are both detected and form a pair. 2MASX J07245535-2430057 and Anon J072448.4-242441: Two galaxy profiles were detected at the 2MASX J07245535-2430057 2MASX-target pointing. While the detection at V_HI = 908 km/s is of 2MASX J07245535-2430057 2MASX J07245535-2430057, the detection at 4638 km/s is from a galaxy visible 2MASX J07245535-2430057 on the 2MASS K-band image (though it is not in the 2MASX catalogue) at 1.0b 2MASX J07245535-2430057 distance (RA,Dec = 07:24:48.4,-24:24:41) which we have confirmed by 2MASX J07245535-2430057 observing this galaxy directly. Anon J072448.4-242441 and 2MASX J07245535-2430057: Two galaxy profiles were detected at the Anon J072448.4-242441 2MASX-target pointing. While the detection at V_HI = 908 km/s is of Anon J072448.4-242441 2MASX J07245535-2430057, the detection at 4638 km/s is from a galaxy visible Anon J072448.4-242441 on the 2MASS K-band image (though it is not in the 2MASX catalogue) at 1.0b Anon J072448.4-242441 distance (RA,Dec = 07:24:48.4,-24:24:41) which we have confirmed by Anon J072448.4-242441 observing this galaxy directly. 2MASX J07403156-2618279 Our central HI velocity of 3578+/-4 km/s is 609 km/s higher than the published 2MASX J07403156-2618279 optical velocity of 2969 km/s (Yamada et al. 1994MNRAS.270...93Y), with 2MASX J07403156-2618279 unknown uncertainty (please note that the 2953 km/s reported in Yamada et al. 2MASX J07403156-2618279 1993ApJS...89...57Y was a preliminary value only). Since neither optical 2MASX J07403156-2618279 measurement is listed in the 2MRS catalogue (Huchra et al. 2MASX J07403156-2618279 2012ApJS..199...26H), we consider our detection as reliable. 2MASX J07483070-2532370 Our central HI velocity of 4389+/-8 km/s is 414 km/s higher than the published 2MASX J07483070-2532370 optical velocity of 3975 km/s (Yamada et al. 1994MNRAS.270...93Y) which, 2MASX J07483070-2532370 however, the authors labeled as uncertain as it is based on a marginal line 2MASX J07483070-2532370 detection. 2MASX J07483252-2516431 Our HI detection appears to be due to nearby 2MASX J07483452-2513191 at 0.4b 2MASX J07483252-2516431 which at K^o = 11.3 mag is just below our sample cut off. There is another 2MASX J07483252-2516431 spiral galaxy within the beam at 0.8b distance, 2MASX J07483666-2510211 2MASX J07483252-2516431 (K^o = 11.2 mag). All three appear to be of similar size. The latter has a 2MASX J07483252-2516431 published NRT HI velocity of 6809 km/s (Paturel et al. 2003A&A...412...57P) 2MASX J07483252-2516431 with a flux (~4.5 Jy km/s) comparable to ours, which would indicate that the 2MASX J07483252-2516431 HI source lies between these two pointings and thus 2MASX J07483452-2513191 2MASX J07483252-2516431 appears to be the detected galaxy. There is also a Parkes HIZOA detection 2MASX J07483252-2516431 (J0748-25B; Staveley-Smith et al. 2016AJ....151...52S) at 2MASX J07483252-2516431 (RA,Dec = 07:48:33.56,-25:14:34.6) and V_HI = 6809 km/s which is nearer to 2MASX J07483252-2516431 2MASX J07483452-2513191 and which has a higher flux (7.3 Jy km/s). 2MASX J07545229-2756453 This lopsided HI detection comes from ESO 430-G001 at 2.8b distance, which was 2MASX J07545229-2756453 detected as HIZOA J0755-28 at Parkes by Staveley-Smith et al. 2MASX J07545229-2756453 2016AJ....151...52S with a peak flux density of ~250 mJy. We only see the 2MASX J07545229-2756453 low velocity horn of the HIZOA profile which goes up to ~1800 km/s. 2MASX J08191136-3833104 The HI detection comes from the Parkes source HIZOA J0818-38 which has a 2MASX J08191136-3833104 visible counterpart at (RA,Dec = 08:18:53.6,-38:41:51), at 2.1b distance 2MASX J08191136-3833104 (Staveley-Smith et al. 2016AJ....151...52S). Their peak flux density is 2MASX J08191136-3833104 ~70 mJy while ours is only ~25 mJy. 2MASX J15394772-3454550 and J15400064-3451570: The lopsided HI detection in our sample observation of 2MASX J15394772-3454550 2MASX J15400064-3451570 at V_HI = 4872 km/s is the detection of 2MASX J15394772-3454550 2MASX J15394772-3454550 (ESO 388- G?005) at 1.5b which we also observed and 2MASX J15394772-3454550 detected as symmetric double-horn profile at V_HI = 4929 km/s . 2MASX J15394772-3454550 2MASX J15400064-3451570 has also an optical velocity measurement of 2MASX J15394772-3454550 4850+/-15 km/s (Huchra et al. 2012ApJS..199...26H) which coincides with the 2MASX J15394772-3454550 HI velocity: we can not exclude that faint emission at or near the detected 2MASX J15394772-3454550 profile may come from this galaxy. 2MASX J15400064-3451570 and J15394772-3454550: The lopsided HI detection in our sample observation of 2MASX J15400064-3451570 2MASX J15400064-3451570 at V_HI = 4872 km/s is the detection of 2MASX J15400064-3451570 2MASX J15394772-3454550 (ESO 388- G?005) at 1.5b which we also observed and 2MASX J15400064-3451570 detected as symmetric double-horn profile at V_HI = 4929 km/s . 2MASX J15400064-3451570 2MASX J15400064-3451570 has also an optical velocity measurement of 2MASX J15400064-3451570 4850+/-15 km/s (Huchra et al. 2012ApJS..199...26H) which coincides with the 2MASX J15400064-3451570 HI velocity: we can not exclude that faint emission at or near the detected 2MASX J15400064-3451570 profile may come from this galaxy. 2MASS J16182186-3730298 and Anon J161826.2-373604, 2MASX J16182851-3739379 and J16183236-3723459: 2MASS J16182186-3730298 There are four larger galaxies in the area, all of which we observed. Two of 2MASS J16182186-3730298 them are in our 2MASX sample, unlike the third, a late-type spiral visible 2MASS J16182186-3730298 on DSS images at 0.4b distance (RA,Dec = 16:18:26.2, -37:36:04) from 2MASS J16182186-3730298 2MASX J16182851-3739379. Between 2MASX J16182851-3739379 and 2MASS J16182186-3730298 2MASX J16183236-3723459 at 1.1b and 1.3b, respectively, is a fourth galaxy 2MASS J16182186-3730298 that is listed only in the 2MASS point source catalogue (Cutri et al. 2MASS J16182186-3730298 2003yCat.2246....0C), 2MASS J16182186-3730298, which is labeled a Young 2MASS J16182186-3730298 Stellar Object candidate by Spezzi et al. 2011ApJ...730...65S; the images, 2MASS J16182186-3730298 however, show an early type galaxy between bright stars. We conclude that the 2MASS J16182186-3730298 strong signal at 4500-4700 km/s appearing in all our spectra is the detection 2MASS J16182186-3730298 of Anon J161826.2-373604. As 2MASX J16183236-3723459 is the only one to show 2MASS J16182186-3730298 a high-velocity shoulder (4700-4900 km/s) in its spectrum, this is likely to 2MASS J16182186-3730298 be from this galaxy. Its optical velocity of 4718+/-96 km/s (Huchra et al. 2MASS J16182186-3730298 2012ApJS..199...26H) agrees with this. Its HI parameters in our tables are 2MASS J16182186-3730298 taken from this shoulder only and are uncertain since the low-velocity end 2MASS J16182186-3730298 of its profile is unknown.

We conclude that 2MASX J16463421-3903086 their profile is confused and dominated by an LSB galaxy visible outside of 2MASX J16463421-3903086 the NRT beam. 2MASX J16490239-3642570 The published optical velocity of 30,028+/-119 km/s (Huchra et al. 2MASX J16490239-3642570 2012ApJS..199...26H) does not agree at all with our clear HI detection at 2MASX J16490239-3642570 6385 km/s. However, with an extinction corrected K-band diameter of 71: and 2MASX J16490239-3642570 K-band magnitude of 10.55 mag our relatively low velocity seems to be the 2MASX J16490239-3642570 more likely one. 2MASX J18002449-0401023 The profile is confused. There are four 2MASS galaxies in the area, one of 2MASX J18002449-0401023 which is not in our sample (2MASX J18001508-0359563 with K^o = 12.3 mag, at a 2MASX J18002449-0401023 distance of 1.3b to the west of the target). The other two 2MASX J18002449-0401023 (2MASX J18003191-0400533 at 1.0b and 2MASX J18003399-0401443 at 1.4b to the 2MASX J18002449-0401023 east) we did not observe since they have HI detections in the literature. 2MASX J18002449-0401023 Paturel et al. 2003A&A...412...57P observed 2MASX J18003191-0400533 at 2MASX J18002449-0401023 4210 km/s with a confused profile similar to ours but with a fainter 2MASX J18002449-0401023 high-velocity shoulder. Their flux is 5.5 Jy km/s as compared to our 2MASX J18002449-0401023 8.8 Jy km/s 2MASX J18003399-0401443 has been cross-matched with 2MASX J18002449-0401023 HIPASS J1800-03 (Meyer et al. 2004MNRAS.350.1195M) in NED and the 2MRS 2MASX J18002449-0401023 catalogue, but the actual position of the HIPASS detection is 2MASX J18002449-0401023 (RA,Dec =18:00:31.9,-04:00:53) at only 0.4b north-east of our target. 2MASX J18002449-0401023 Kraan-Korteweg et al. (in prep.) detected in their blind HI survey of the 2MASX J18002449-0401023 Galactic bulge area using Parkes a similarly confused profile at 2MASX J18002449-0401023 (RA,Dec = 18:00:17.9,-03:59:41; HIZOA J1800-03) with a higher flux of 2MASX J18002449-0401023 11.8 Jy km/s. Their profile shows a peak at ~4350 km/s which is more 2MASX J18002449-0401023 pronounced (S+p = 50 mJy) than in our profile (S_p = 30 mJy) or that of 2MASX J18002449-0401023 Paturel et al. (S_p = 8 mJy). After careful comparison of the different 2MASX J18002449-0401023 profiles we conclude that most of the HIZOA J1800-03 detection comes from 2MASX J18002449-0401023 2MASX J18001508-0359563 which is >2b from 2MASX J18003191-0400533 that 2MASX J18002449-0401023 Paturel et al. observed. Our detection seems to be a confused profile of 2MASX J18002449-0401023 mainly the target (2MASX J18002449-0401023) and 2MASX J18003191-0400533 2MASX J18002449-0401023 (~4100-4300 km/s) with some contribution by 2MASX J18001508-0359563 at the 2MASX J18002449-0401023 high velocity end, which is more pronounced in our profile than in the one by 2MASX J18002449-0401023 Paturel et al. It is not possible to tell whether 2MASX J18003399-0401443 2MASX J18002449-0401023 contributes to the profiles at all, but it is clear that it cannot be the 2MASX J18002449-0401023 main cross-match of HIPASS J1800-03. 2MASX J18073699-0850329 This is actually a detection of nearby Parkes source HIZOA J1807-08 2MASX J18073699-0850329 (Staveley-Smith et al. 2016AJ....151...52S) with a flux of 24.0 Jy km/s 2MASX J18073699-0850329 (compared to our 4.6 Jy km/s) and a reported visible counterpart at 1.2b 2MASX J18073699-0850329 from our pointing position (at RA,Dec = 18:07:35.5,-08:37:40). 2MASX J18513759-0859297 This is actually a detection of nearby Parkes source HIZOA J1851-09 2MASX J18513759-0859297 (Staveley-Smith et al. 2016AJ....151...52S) with an HI flux of 7.5 Jy km/s 2MASX J18513759-0859297 (compared to our 1.4 Jy km/s) and a reported visible counterpart at 1.7b 2MASX J18513759-0859297 distance from our pointing position (at RA,Dec = 18:51:27.4,-09:10:47). 2MASX J19502869+1822386 and J19505731+1822281: The 2MASX J19502869+1822386 observation shows two 2MASX J19502869+1822386 detections, neither of which is of the target. The double-horned profile at 2MASX J19502869+1822386 V_HI = 3972 km/s clearly comes from 2MASXJ 19505731+1822281, a nearly 2MASX J19502869+1822386 edge-on medium-type spiral at a distance of 3.8b which we also observed 2MASX J19502869+1822386 directly and where we detected twice the flux observed towards the target. 2MASX J19502869+1822386 This nearby galaxy also accounts for the Arecibo HI detection reported by 2MASX J19502869+1822386 Lu et al. 1990ApJ...357..388L at V_HI = 3978 km/s and the Parkes HIPASS 2MASX J19502869+1822386 detection J1950+18b (Wong et al. 2006MNRAS.371.1855W) with a flux of 2MASX J19502869+1822386 17.6 Jy km/s which is almost twice our flux of 2MASX J19505731+1822281. 2MASX J19502869+1822386 The difference is likely due to the narrow NRT beam which does not cover 2MASX J19502869+1822386 the full HI disc. Martin et al. 1990A&A...235...41M who also used the NRT 2MASX J19502869+1822386 to observe this target. Their flux (F_HI = 1.82 Jy km/s) and profile shape 2MASX J19502869+1822386 are comparable to ours. There is another Parkes detection, HIPASS J1950+18a 2MASX J19502869+1822386 (Wong et al. 2006MNRAS.371.1855W), at 1.6b distance with a higher flux of 2MASX J19502869+1822386 9.2 Jy km/s. Both its distance and flux indicate that the detection is not 2MASX J19502869+1822386 from our target. No visible counterpart could be found. 2MASX J19505731+1822281 and J19502869+1822386: The 2MASX J19502869+1822386 observation shows two 2MASX J19505731+1822281 detections, neither of which is of the target. The double-horned profile at 2MASX J19505731+1822281 V_HI = 3972 km/s clearly comes from 2MASXJ 19505731+1822281, a nearly 2MASX J19505731+1822281 edge-on medium-type spiral at a distance of 3.8b which we also observed 2MASX J19505731+1822281 directly and where we detected twice the flux observed towards the target. 2MASX J19505731+1822281 This nearby galaxy also accounts for the Arecibo HI detection reported by 2MASX J19505731+1822281 Lu et al. 1990ApJ...357..388L at V_HI = 3978 km/s and the Parkes HIPASS 2MASX J19505731+1822281 detection J1950+18b (Wong et al. 2006MNRAS.371.1855W) with a flux of 2MASX J19505731+1822281 17.6 Jy km/s which is almost twice our flux of 2MASX J19505731+1822281. 2MASX J19505731+1822281 The difference is likely due to the narrow NRT beam which does not cover 2MASX J19505731+1822281 the full HI disc. Martin et al. 1990A&A...235...41M who also used the NRT 2MASX J19505731+1822281 to observe this target. Their flux (F_HI = 1.82 Jy km/s) and profile shape 2MASX J19505731+1822281 are comparable to ours. There is another Parkes detection, HIPASS J1950+18a 2MASX J19505731+1822281 (Wong et al. 2006MNRAS.371.1855W), at 1.6b distance with a higher flux of 2MASX J19505731+1822281 9.2 Jy km/s. Both its distance and flux indicate that the detection is not 2MASX J19505731+1822281 from our target. No visible counterpart could be found. 2MASX J20084824+4339589 and J20085388+4338070: Their HI profiles are mutually confused. The two 2MASX J20084824+4339589 galaxies are 0.6b apart and the profile of 2MASX J20085388+4338070 clearly 2MASX J20084824+4339589 also shows the same two peaks observed towards 2MASX J20084824+4339589. 2MASX J20084824+4339589 The latter is the more inclined object. Both galaxies have optical 2MASX J20084824+4339589 velocities: 5031+/-63 km/s and 4916+/-13 km/s, respectively (Huchra et al. 2MASX J20084824+4339589 2012ApJS..199...26H). This is consistent with the low-velocity shoulder 2MASX J20084824+4339589 (at V_HI ~ 4700-4900 km/s) coming from 2MASX J20085388+4338070 (where the 2MASX J20084824+4339589 flux density is also higher). 2MASX J20085388+4338070 and J20084824+4339589: Their HI profiles are mutually confused. The two 2MASX J20085388+4338070 galaxies are 0.6b apart and the profile of 2MASX J20085388+4338070 clearly 2MASX J20085388+4338070 also shows the same two peaks observed towards 2MASX J20084824+4339589. 2MASX J20085388+4338070 The latter is the more inclined object. Both galaxies have optical 2MASX J20085388+4338070 velocities: 5031+/-63 km/s and 4916+/-13 km/s, respectively (Huchra et al. 2MASX J20085388+4338070 2012ApJS..199...26H). This is consistent with the low-velocity shoulder 2MASX J20085388+4338070 (at V_HI ~ 4700-4900 km/s) coming from 2MASX J20085388+4338070 (where the 2MASX J20085388+4338070 flux density is also higher). 2MASX J20194861+4046363 and J20201209+4039396: The profile of 2MASX J20194861+4046363 seems to come 2MASX J20194861+4046363 entirely from 2MASX J20201209+4039396 which lies 2.5b to the east: their 2MASX J20194861+4046363 profiles are centred on 4229 and 4225 km/s, respectively, and the flux of 2MASX J20194861+4046363 2MASX J20201209+4039396 is more than three times higher. We also find that 2MASX J20194861+4046363 the HI profiles of both objects show a barely resolved (W_50 = 24 km/s, at 2MASX J20194861+4046363 18 km/s resolution) non-RFI spike at 4470 km/s. The flux ration is similar to 2MASX J20194861+4046363 the broad profile which would argue that it could be emission connected with 2MASX J20194861+4046363 2MASX J20201209+4039396. The angular separation between the two objects 2MASX J20194861+4046363 (2.5b) is large enough that in-beam confusion between them can be excluded. 2MASX J20194861+4046363 The observations were acquired over a period spanning 8 years and the narrow 2MASX J20194861+4046363 spike is detected in all observations. 2MASX J20201209+4039396 and J20194861+4046363: The profile of 2MASX J20194861+4046363 seems to come 2MASX J20201209+4039396 entirely from 2MASX J20201209+4039396 which lies 2.5b to the east: their 2MASX J20201209+4039396 profiles are centred on 4229 and 4225 km/s, respectively, and the flux of 2MASX J20201209+4039396 2MASX J20201209+4039396 is more than three times higher. We also find that 2MASX J20201209+4039396 the HI profiles of both objects show a barely resolved (W_50 = 24 km/s, at 2MASX J20201209+4039396 18 km/s resolution) non-RFI spike at 4470 km/s.

The angular separation between the two objects 2MASX J20201209+4039396 (2.5b) is large enough that in-beam confusion between them can be excluded. 2MASX J20201209+4039396 The observations were acquired over a period spanning 8 years and the narrow 2MASX J20201209+4039396 spike is detected in all observations. 2MASX J20440241+5043362 The classic double-horn shape of this triple-peaked profile, centred on 2MASX J20440241+5043362 V_HI ~ 3350 km/s, actually comes from nearby 2MASX J20435702+5032583 (also 2MASX J20440241+5043362 observed by us), at 1.0b distance to the south, whereas the fainter HI from 2MASX J20440241+5043362 the target galaxy appears at the low-velocity end (V_HI ~ 2900-3150 km/s). 2MASX J20440241+5043362 This agrees also with the target's optical velocity of 3113+/-24 km/s 2MASX J20440241+5043362 (Huchra et al. 2012ApJS..199...26H). Masters et al. 2014MNRAS.443.1044M 2MASX J20440241+5043362 observed this galaxy with the GBT, which has a more than two times smaller 2MASX J20440241+5043362 beam width in the N-S direction than the NRT, and detected an unconfused 2MASX J20440241+5043362 profile at ~2900-3300 km/s. The HI parameters in our tables are taken from 2MASX J20440241+5043362 the low-velocity shoulder only and are therefore uncertain. 2MASX J20540993+4608346 It is likely that this is actually an HI detection of a close-by LSB galaxy at 2MASX J20540993+4608346 0.2b (RA,Dec = 20:54:07.9,+46:09:32). The narrow (W_50 = 65 km/s), single 2MASX J20540993+4608346 peak profile and low HI mass (log(M_HI) = 9.0) does not match the 2MASX J20540993+4608346 inclined-spiral aspect of the target. 2MASX J21060821+4500472 and J21061631+4503203: These two galaxies are 0.8b apart and both show 2MASX J21060821+4500472 confused profiles: The double horn profile obvious in the pointing of 2MASX J21060821+4500472 2MASX J21061631+4503203 (at V_HI ~ 5150-5625 km/s) appears also in the 2MASX J21060821+4500472 observation of 2MASX J21060821+4500472 but at a ~25% lower peak flux density 2MASX J21060821+4500472 level, while the high-velocity shoulder (up to ~5750 km/s) seems to come 2MASX J21060821+4500472 from 2MASX J21060821+4500472 proper. 2MASX J21061631+4503203 and J21060821+4500472: These two galaxies are 0.8b apart and both show 2MASX J21061631+4503203 confused profiles: The double horn profile obvious in the pointing of 2MASX J21061631+4503203 2MASX J21061631+4503203 (at V_HI ~ 5150-5625 km/s) appears also in the 2MASX J21061631+4503203 observation of 2MASX J21060821+4500472 but at a ~25% lower peak flux density 2MASX J21061631+4503203 level, while the high-velocity shoulder (up to ~5750 km/s) seems to come 2MASX J21061631+4503203 from 2MASX J21060821+4500472 proper. 2MASX J21132159+4945237 and 2MASX J21132528+4956168: Their profiles are mutually confused, and may 2MASX J21132159+4945237 also contain a detection of another galaxy. We observed both objects, which 2MASX J21132159+4945237 are separated by 0.9b and whose profiles cannot be disentangled. Neither has 2MASX J21132159+4945237 an optical velocity. There seem to be two (or more) HI detections in our 2MASX J21132159+4945237 spectrum of 2MASX J21132159+4945237. The low-velocity profile 2MASX J21132159+4945237 (V_HI ~ 5600-6050 km/s) appears to come from the target since towards 2MASX J21132159+4945237 2MASX J21132528+4956168 the peak flux density of the same profile is half of 2MASX J21132159+4945237 that observed towards 2MASX J21132159+4945237. It is not possible to tell 2MASX J21132159+4945237 whether all of the profile at V_HI > 6050 km/s or only parts thereof come 2MASX J21132159+4945237 from 2MASX J21132528+4956168, whether it may overlap with the former profile, 2MASX J21132159+4945237 and if a third galaxy (located at about equal distance between these two) may 2MASX J21132159+4945237 be involved. Note that nothing is visible on DSS and UKIDSS images though at 2MASX J21132159+4945237 the high extinction of A_K = 0.75 mag a hidden blue LSB galaxy cannot be 2MASX J21132159+4945237 excluded. 2MASX J21132528+4956168 and 2MASX J21132159+4945237: Their profiles are mutually confused, and may 2MASX J21132528+4956168 also contain a detection of another galaxy.

There seem to be two (or more) HI detections in our 2MASX J21132528+4956168 spectrum of 2MASX J21132159+4945237. The low-velocity profile 2MASX J21132528+4956168 (V_HI ~ 5600-6050 km/s) appears to come from the target since towards 2MASX J21132528+4956168 2MASX J21132528+4956168 the peak flux density of the same profile is half of 2MASX J21132528+4956168 that observed towards 2MASX J21132159+4945237.

We also observed this object 2MASX J21305323+4813559 (which is in our sample) and found F_HI = 8.6 Jy km/s, which is comparable to 2MASX J21305323+4813559 the Paturel et al. measurement. Our target 2MASX J21305323+4813559 has an 2MASX J21305323+4813559 optical velocity of 3556 km/s (Seeberger et al. 1998A&AS..127..101S) without 2MASX J21305323+4813559 a quoted uncertainty. We do not see any trace of a second detection in 2MASX J21305323+4813559 our spectrum. 2MASX J21512814+5316383 This is a marginal HI detection (V_HI = 4658 km/s and F_HI = 2.3 Jy km/s) of 2MASX J21512814+5316383 a nearby galaxy, 2MASX J21514071+5326542 at 1.3b distance. At the VLA, 2MASX J21512814+5316383 Henning 1992ApJS...78..365H measured V_HI = 4715 km/s, W_20 = 326 km/s and 2MASX J21512814+5316383 F_HI = 12 Jy km/s, while at the NRT Martin et al. 1990A&A...235...41M 2MASX J21512814+5316383 measured V_HI = 4700 km/s, W_20 = 359 km/s and F_HI = 6 Jy km/s. Though 2MASX J21512814+5316383 clearly we detected the same profile, ours is slightly wider at 2MASX J21512814+5316383 W_20 = 486 km/s. It is not clear whether this is due to noise peaks 2MASX J21512814+5316383 (our peak flux density to rms ratio is only 5.0) or whether we detected a 2MASX J21512814+5316383 weak flux from the target 2MASX J21512814+5316383 proper. We therefore list 2MASX J21512814+5316383 this galaxy as not detected. 2MASX J22540054+6728086 Our central HI velocity of 4328+/-12 km/s is 439 km/s lower than the published 2MASX J22540054+6728086 optical velocity of 4767 km/s (Nakanishi et al. 1997ApJS..112..245N), 2MASX J22540054+6728086 for which no uncertainty is given and which is listed as based on a private 2MASX J22540054+6728086 communication (Saunders 1997: IRAS PSC Redshift Survey). No later published 2MASX J22540054+6728086 trace of this measurement could be found. On the other hand, 2MASX J22540054+6728086 2MASX J22540054+6728086 was also detected in HI by Masters et al. 2MASX J22540054+6728086 2014MNRAS.443.1044M with the GBT at V_HI = 4335 km/s and similar flux. 2MASX J21584706+5408535 This is actually a detection of a nearby (0.6b distance) LSB galaxy at 2MASX J21584706+5408535 (RA,Dec = 21:58:40.0,+54:12:05, visible only on UKIDSS images) Schroeder et 2MASX J21584706+5408535 al. 2019b, 2019MNRAS.489.2907S detected it as EBHIS-ZoA source EZOA J2158+54 2MASX J21584706+5408535 at Effelsberg with a flux of 4.9 Jy km/s and a slightly higher rms. Our 2MASX J21584706+5408535 detection has a larger W_20 of 153 km/s (versus 94 km/s for EZOA J2158+54) 2MASX J21584706+5408535 due to a high-velocity shoulder which might come from 2MASX J21584706+5408535 2MASX J21584706+5408535 proper.
