10 This source has a redshift listed in NED that was not reported in table2 10 because we were unable to trace back to its original source. 19 This source has a redshift listed in NED that was not reported in table2 19 because we were unable to trace back to its original source. 30 This source has a redshift listed in NED that was not reported in table2 30 because we were unable to trace back to its original source. 33 Redshift was obtained from a pre-release version of the final redshift 33 catalogue from the 6dF Galaxy Survey (Cat. ). 42 This source has a redshift listed in NED that was not reported in table2 42 because it was considered to be unreliable. 57 Lies so close to bright foreground stars that no optical identification is 57 possible from the DSS images. 61 PKS 0454-81 appears in the scan maps, but the follow-up data were degraded 61 by bad weather and we did not have the opportunity to re-observe it. 61 For this source we obtained a flux density measurement from its 61 observations as a secondary calibrator in 2006 October. 68 The spectra showed a featureless optical continuum from which no redshift 68 could be measured. 73 Lies within the boundaries of the Large Magellanic Cloud and its 73 identification is uncertain. 77 Redshift measurement from optical spectra obtained at the ANU 2.3-m 77 telescope in 2007 April and June by R. W. Hunstead and two of the authors 77 (P. J. Hancock and E. Mahony). 78 The spectra showed a featureless optical continuum from which no redshift 78 could be measured. 85 This source has a redshift listed in NED that was not reported in table2 85 because we were unable to trace back to its original source. 92 (PKS 0637-752) is a quasar with an asymmetric jet seen in radio and X-ray 92 images (Schwartz et al., 2000ApJ...540L..69S). The tabulated flux density 92 is dominated by the core with about 10% in the 15-arcsec jet. It is one of 92 the largest (100kpc) and most luminous jets known with properties 92 similar to 3C273. 98 Redshift measurement from optical spectra obtained at the ANU 2.3-m 98 telescope in 2007 April and June by R. W. Hunstead and two of the authors 98 (P. J. Hancock and E. Mahony). 109 (PMN J08355953) has a highly inverted radio spectra, with spectral index 109 alpha^20^_5_=+0.88, but has no obvious optical counterpart. Although the 109 Galactic latitude is relatively low (b=11{deg}), the optical extinction is 109 only 1.1mag in the B band. The lack of optical ID suggests this could be a 109 distant radio galaxy rather than a QSO. 138 redshift has been measured with the ESO 3.6-m telescope by P. G. Edwards and 138 his collaborators (Edwards et al., in preparation). 140 Redshift measurement from optical spectra obtained at the ANU 2.3-m 140 telescope in 2007 April and June by R. W. Hunstead and two of the authors 140 (P. J. Hancock and E. Mahony). 151 (PKS 1143-696) is a resolved double in the SUMSS image, and is also double 151 in the 20-GHz image. The SUMSS source is larger than the ATCA beam at 151 20GHz, suggesting that the measured flux density may be a lower limit to 151 the true value. The position of the low-frequency radio centroid is 151 slightly different from the AT20G position. 160 Lies so close to bright foreground stars that no optical identification is 160 possible from the DSS images. 162 Redshift measurement from optical spectra obtained at the ANU 2.3-m 162 telescope in 2007 April and June by R. W. Hunstead and two of the authors 162 (P. J. Hancock and E. Mahony). 166 Redshift measurement from optical spectra obtained at the ANU 2.3-m 166 telescope in 2007 April and June by R. W. Hunstead and two of the authors 166 (P. J. Hancock and E. Mahony). 208 Redshift measurement from optical spectra obtained at the ANU 2.3-m 208 telescope in 2007 April and June by R. W. Hunstead and two of the authors 208 (P. J. Hancock and E. Mahony). 211 (PKS 1548-79) is a relatively nearby (z=0.15) galaxy with an unresolved 211 radio 211 source which has a steep spectrum in our 5-, 8- and 20-GHz data. 211 The galaxy has strong optical emission lines, and has been studied in 211 detail by Tadhunter et al. (2001MNRAS.327..227T). 221 appears to be one component of a source (PKS 1622-29) which is double 221 (component separation ~1.5arcmin) in the NVSS image. Both components fall 221 within the ATCA 5-GHz beam, but the 20-GHz image is centred on the eastern 221 component and the other component falls outside the primary beam. Our 221 measured 20-GHz flux density is therefore an underestimation of the total 221 flux density. This source has a redshift listed in NED that was not 221 reported in table2 because we were unable to trace back to its original 221 source. 246 Redshift measurement from optical spectra obtained at the ANU 2.3-m 246 telescope in 2007 April and June by R. W. Hunstead and two of the authors 246 (P. J. Hancock and E. Mahony). 258 The AT20G source (corresponding to PKS 1932-46) is flagged as extended, and 258 the image appears to show a compact double. The source is a 30arcsec double 258 at 5GHz (Duncan & Sproats, 1992PASAu..10...16D). The optical position given 258 in NED is associated with a z=0.231 galaxy at (J2000) 19:35:56.5 46:20:41, 258 which is offset by 3.2arcsec from the AT20G position but appears to be the 258 correct ID. 273 (PKS 2052-47) is a z=1.5 QSO which is also detected as both an X-ray and a 273 gamma-ray source. Since this source is an ATCA calibrator, its flux density 273 has been monitored at several epochs during 2002-07. The calibrator data 273 suggest that our AT20G observation of this object in 2004 October took 273 place during the declining stage of a flaring phase, during which the flux 273 density of the source changed rapidly. This fast change in flux and 273 polarization properties is clearly visible in our data, with the 20-GHz 273 flux density decreasing by a factor of 2.5 in 2d. This makes it difficult 273 to give a reliable value for the flux density and fractional polarization 273 of this source. 278 This source has a redshift listed in NED that was not reported in table2 278 because we were unable to trace back to its original source. 292 (PKS 2227-3952) is a resolved triple in the SUMSS image. The low-frequency 292 emission extends somewhat beyond the 20-GHz ATCA beam, but the source is 292 not flagged as extended here, since the 20-GHz flux is dominated by 292 the core. 310 flagged as extended, appears to be the core of a well-known and highly 310 extended radio galaxy PKS 2331-240. The optical ID is a galaxy at z=0.0477. 310 The extended flux is well outside of the primary beam used for these 310 observations and the flux densities listed correspond mainly to the core. 313 Redshift was obtained from a pre-release version of the final redshift 313 catalogue from the 6dF Galaxy Survey (Cat. ). 319 (PKS 2356-61) is a FanaroffRiley type II galaxy characterized by four bright 319 regions of emissions that are slightly asymmetric about the core 319 (Burke et al., in preparation).
