A2746_2a/b (P=0.03) The radio morphology suggests a possible A2746_2a/b wide-angle tailed (WAT) radio galaxy with the host G near the A2746_2a/b radio centroid. A2746_8 (P=0.0005) The St object near the radio centroid is A2746_8 accepted as the identification, but the fainter G~4" to the east, A2746_8 with P=0.008, may be an alternative identification. A2837_1 (P=0.0002) Fig. 3 shows an unambiguous identification A2837_1 with a G near the source centroid. A2837_6 (P=0.0008) The most likely identification is the G A2837_6 near the source centroid, but a fainter G (P=0.03) near the radio A2837_6 axis 10" to the NE may be the host of an unresolved narrow-angle A2837_6 tailed (NAT) radio galaxy. A2837_8 Although no identification is listed, Fig. 3 shows A2837_8 a G 13" to the south of the radio centroid (P=0.08) that may be A2837_8 the host of an unresolved WAT. A2837_9 (P=0.002) A faint G near the radio centroid is not A2837_9 clear in the R-band image of Fig. 3, but is verified by the B A2837_9 and IR images. The two brighter G's to the NE and NW of the A2837_9 centroid could be hosts to either an unresolved NAT (P=0.002) A2837_9 or WAT (P=0.002) respectively; they are probably cluster galaxies. A2837_10 (P=0.0005) The faint G in Fig. 3, 1" to the NNW of A2837_10 the radio centroid, is confirmed on UKST-B and ESO-R images. A2837_11 (P=0.006) The bright G, 8" to the ENE, could be a A2837_11 cluster member. and is accepted as the identification. The faint A2837_11 object near the radio centroid appears only on the 2nd-epoch Sky A2837_11 Survey B-image, but not on the 1st-epoch one, and is therefore A2837_11 probably a plate defect. A2837_14 (P=0.005) Figure 3 shows a G, 4" to the NE of the A2837_14 radio centroid which we accept as the identification. The object A2837_14 is not bright enough for cluster membership. The faint object ~15" A2837_14 to the west has a high probability of projection. A3126_2 The St 7" to the south of the radio centroid has A3126_2 P=0.02, but its position relative to the radio centroid and major A3126_2 axis does not support its status as an identification. A3126_9 The bright G is a secure identification for this A3126_9 extended source. It is a cluster member by its brightness. A3126_10a/b The well-defined double source is probably a distant A3126_10a/b FR II radio galaxy. A3126_13/16 Here we see two separate sources, one extended A3126_13/16 (#13, NW) and the other (#16, SE) much more compact; both are A3126_13/16 identified with bright elliptical galaxies, in fact the two A3126_13/16 brightest are spectroscopically confirmed cluster members, which A3126_13/16 are projected onto the cluster at angular distances of 1.0' and A3126_13/16 0.2' from the X-ray centroid respectively. The compact SE source A3126_13/16 (#16) coincides with the brightest cluster galaxy and is A3126_13/16 closer in projection to the cluster's X-ray centroid. Given the A3126_13/16 positional uncertainty of ~1' of the REFLEX position for an A3126_13/16 extended source like this (Edge 2006, priv. comm.), A3216_16 and its A3126_13/16 associated galaxy could well be at the dynamical centre of the A3126_13/16 cluster. There is good evidence from the digitized image of A3126_13/16 the 2-nd epoch UKST Red Survey for a halo surrounding them. Another A3126_13/16 unusual feature of this pair of radio sources is the marked A3126_13/16 difference in their radio spectra. The compact SE source has a A3126_13/16 fairly flat spectrum (alpha=-0.27+/-0.54), while the extended NW A3126_13/16 source has a more normal spectral index of -0.90+/-0.16. The flat A3126_13/16 spectrum and compact nature of the SE source suggest that this A3126_13/16 elliptical is dominated by an AGN, while the NW source is possibly a A3126_13/16 partially resolved NAT whose projected tails extend almost to the A3126_13/16 cluster's X-ray centroid. A3126_25 (P=0.0013) The comparatively bright St object, 6" to A3126_25 the NNW of the radio centroid, is accepted as the identification A3126_25 for this extended source. A3126_27 (P=0.0003) The faint G near the centroid of A3126_27 this extended radio source is accepted as the most likely A3126_27 identification. The St object 22" to the NNW of the centroid has A3126_27 P=0.23 and is not associated with the radio source. A3126_28 (P=0.005) The comparatively bright G, 5" to the SSW A3126_28 of the radio centroid, is accepted as the identification. A3216_2 (P=0.00003) The bright elliptical G near the radio A3216_2 centroid is accepted as the identification, and considered a A3216_2 cluster member. A3216_6a/b (P=0.00009) The comparatively bright G near the A3216_6a/b radio centroid is accepted as the identification, and considered A3216_6a/b a cluster member. The fainter St object, 7" to the NNE, may be A3216_6a/b a projected object with P=0.023. A3216_7 The extended source is probably an unresolved NAT; A3216_7 the host G is 16" to the NE of the radio centroid along the major A3216_7 axis. Its probability of projection is P=0.06 with respect to A3216_7 the radio centroid, but its proximity to the major axis makes A3216_7 the identification more secure. A3216_9 (P=0.00006) The bright G near the radio centroid is A3216_9 the favoured identification, but the other three G's within the A3216_9 central two contours are bright enough to be cluster members; A3216_9 they have values of P between 0.01 and 0.00007. A3216_10 (P=0.004) Although the G is displaced 9" from A3216_10 the radio centroid along the major axis, it is accepted as the A3216_10 identification for this radio source. It is bright enough for A3216_10 cluster membership. A3216_14 A bright St object (m_R=13.7) is 4.4" from the A3216_14 radio centroid of this unresolved source, but its accurate radio A3216_14 coordinates suggest that the objects are not associated. There A3216_14 is no overlay in Fig. 3. A3230_1 Figure 3 shows four optical objects within the A3230_1 radio contours: three G's and one St (the fainter of the two A3230_1 images to the SW). All four objects within the contours have a A3230_1 low probability of projection with respect to the radio centroid A3230_1 (P<0.01) but only the bright E/S0 galaxy ~20" to the south east of A3230_1 the radio peak, and the brighter of the two fainter galaxies (7" A3230_1 south of the radio peak) are bright enough to be cluster members. A3230_1 The bright E/S0 SE of the radio centroid is accepted as the most A3230_1 likely identification, as it is positioned along the major axis A3230_1 of this extended source. A3230_4 (P=0.0002) The bright elliptical G near the A3230_4 radio centroid is accepted as the identification for this A3230_4 extended source; it is possibly the host galaxy of an unresolved A3230_4 WAT. Despite the clear elongation of the radio contours, a gaussian A3230_4 fit was unable to yield a deconvolved size. A3230_9 (P=0.02) The faint St identification for this extended A3230_9 source is displaced 6" along the major axis to the NNW of the radio A3230_9 centroid. It is tabulated in the UK-R and UK-B SuperCOSMOS data. A3230_11 (P=0.00004) There are two bright G's at 1" and 4" A3230_11 to the south of the radio centroid, but the brighter one nearer A3230_11 the radio centroid is accepted as the identification. The other A3230_11 galaxy is also bright enough for cluster membership. There is A3230_11 no overlay in Fig. 3. A3827_2 Fig. 3 shows no clear identification for this slightly A3827_2 extended source. It is possibly a distant FR II. A3827_3 (P=0.0024) The St object, close to the radio centroid, A3827_3 is accepted as the identification. The faint G, 24" along the major A3827_3 axis to the SSW of the radio centroid, is probably a projected A3827_3 object with P=0.2; this G is too faint to be a cluster member. A3827_4 The bright elliptical G near the radio centroid is A3827_4 clearly the identification. The distorted nature of the outer A3827_4 contour to the SSE may be due to the close negative contour. The A3827_4 source is clearly extended in PA~60{deg}, but a deconvolved size A3827_4 was not yielded in a gaussian fit. A3827_8 (P=0.002) The bright elliptical G to the NNW of A3827_8 the radio centroid of this extended source is accepted as the A3827_8 identification. The relatively bright St near the SSW outer A3827_8 contour may be a projected object with P=0.10. A3827_11a/b The two St objects within the contours of the double A3827_11a/b radio source are likely to be projections with P=0.21 and P=0.24 A3827_11a/b respectively. This is probably a distant FR II radio galaxy. A3827_14 Within the radio contours are an St (24"@78{deg}) and A3827_14 a G (12"@203{deg}). Their projection probabilities are P=0.26 A3827_14 and P=0.08 respectively. The G is not bright enough for cluster A3827_14 membership and neither object is an acceptable identification. A3827_21 (P=0.009) The faint G displaced 5" along the A3827_21 major axis to the NNE of the radio centroid is the accepted A3827_21 identification. We discard the bright galaxy 16" to the SSE of A3827_21 the radio centroid (2MASX J22015849-5943068) as the identification A3827_21 for its separation from the radio centroid and for its significant A3827_21 displacement from the major axis of the radio source. A3827_24a/b The Sp is unlikely to be a projected object whether A3827_24a/b identified with component b (P=0.002) or associated with the A3827_24a/b centroid of the double (P=0.035). The identification in Table 3 A3827_24a/b is with component b, and is bright enough to be a cluster spiral. A3827_26 The faint objects near the outer contour of this A3827_26 extended radio source to the east and north of the radio centroid A3827_26 are likely to be projections with P=0.54 and 0.50 respectively. A3836_9a/b Neither of the components of this apparent double are A3836_9a/b resolved at 2.38 GHz and no identification can be detected. If A3836_9a/b it is a real double, it is probably a distant FR II radio galaxy. A3836_17 The faint St object to the north of the radio centroid A3836_17 is unlikely to be a projection (P=0.02), but its 7" separation A3836_17 from the centroid of the radio source and its offset from the A3836_17 major axis are not consistent with an identification. A3836_19a/b (P=0.11) There is a possibility that the faint G A3836_19a/b between the components is a projected object, but its proximity A3836_19a/b to the major axis of the double improves the security of the A3836_19a/b identification. It is not bright enough for a cluster elliptical.
