Cl1216_06 Source Cl11216_X6 is firmly associated (Pid=92%) with a spiral galaxy
Cl1216_06  found 1'30" from the cluster core which contains a very bright 
Cl1216_06  central point source. The source is not flagged as a possible 
Cl1216_06  cluster member based on photometric properties, but has a 
Cl1216_06  best-fitting redshift when fitted with a quasi-stellar object (QSO) 
Cl1216_06  template of zQSO=0.82. The X-ray source has a full-band flux of 
Cl1216_06  S0.5-8keV=1.6x10^-14^erg/s/cm2 and HR=0.12, consistent with a 
Cl1216_06  moderately obscured AGN
Cl1216_08 source Cl1216_X8 is unambiguously associated with a galaxy found 
Cl1216_08  3'30" from the cluster centre containing a very bright AGN which is 
Cl1216_08  not flagged as a possible cluster member but has zQSO=0.72. However,
Cl1216_08  as the source lies outwith the FOV of the near-IR observations, the 
Cl1216_08  photometric redshift is based on only optical bands and is 
Cl1216_08  considered less reliable. The X-ray source has a full-band flux of 
Cl1216_08  S0.5-8keV=2.1x10^-14^erg/s/cm2 and HR=0.50, consistent with an 
Cl1216_08  unobscured AGN.
Cl1216_26 Source Cl1216_26 is ambiguously associated (Pid=65%) with a galaxy 
Cl1216_26  lying 4arcmin from the cluster centre which is flagged as a possible
Cl1216_26  cluster member based on its photometric properties. However, like 
Cl1216_26  Cl1216_08, this source was not observed in the near-IR and its 
Cl1216_26  photometric redshift is based on only optical bands. As both 
Cl1216_26  photometric redshift codes prefer z~1.5 solutions for this source 
Cl1216_26  and its optical counterpart is very faint, this source is most 
Cl1216_26  likely at a higher redshift than Cl1216.
Cl1216_46 An extended source (Cl1216_X46) is evident at the XMM aim-point, 
Cl1216_46  coincident with a dense concentration of spectroscopically confirmed 
Cl1216_46  cluster members which includes the BCG. 
Cl1216_59 Source Cl1216_X59, lies 3'20" to the north-east of the cluster centre 
Cl1216_59  and is ambiguously identified with a group of three sources based on
Cl1216_59  the WFI imaging. The HST view of this region reveals two fainter 
Cl1216_59  objects also within the X-ray 3{sigma} error ellipse. The brightest 
Cl1216_59  source is flagged as possible cluster member based on its 
Cl1216_59  photometric properties. The X-ray detection has a flux 
Cl1216_59  S0.5-8keV=4.7x10^-15^erg/s/cm2 and HR=0.36, consistent with a 
Cl1216_59  heavily obscured AGN.
Cl1054_09 Source Cl1054_X9 is ambiguously associated with two galaxies located 
Cl1054_09  ~4arcmin south-east of the BCG. The probability of association Pid, 
Cl1054_09  is roughly 50 per cent for both galaxies. The galaxy farther to the 
Cl1054_09  south is given very low membership probabilities (Pmem<2%), whereas
Cl1054_09  the northern galaxy is a spectroscopically confirmed cluster member
Cl1054_09  with no obvious AGN signatures in its optical spectra. The X-ray
Cl1054_09  detection has a flux S0.5-8keV=8.5x10^-14^erg/s/cm2 and HR=0.02,
Cl1054_09  consistent with a moderately obscured AGN.
Cl1054_10 Source Cl1054_X10, the compact source embedded in the eastern side of 
Cl1054_10  the diffuse emission, is unambiguously identified with a galaxy with 
Cl1054_10  a bright AGN core which lies ~1 arcmin from the BCG and is flagged as
Cl1054_10  a cluster candidate (Pmem~75%). The X-ray detection has a flux 
Cl1054_10  S0.5-8keV=5.4x10^-14^erg/s/cm2 and HR=0.5, consistent with an 
Cl1054_10  unobscured AGN. However, as it is likely that the optical colours are
Cl1054_10  affected by the luminous AGN, the validity of the photometric 
Cl1054_10  redshift based on a galaxy template is questionable. zQSO for this 
Cl1054_10  source is ~1.5.
Cl1054_26 Source Cl1054_X26 is unambiguously associated with a galaxy ~3'45" 
Cl1054_26  from the cluster centre which is flagged as a possible cluster 
Cl1054_26  member, though with fairly low probability (Pmem~30%). The source 
Cl1054_26  has disturbed morphology and is faint in both the optical and X-ray 
Cl1054_26  bands, with an X-ray flux of S0.5-8keV=7.2x10^-15^erg/s/cm2 and 
Cl1054_26  HR=0.36, consistent with a heavily obscured AGN.
Cl1040_12 Source Cl1040_X12 is ambiguously associated with two objects ~1'30" 
Cl1040_12  from the cluster core. The object to the west is a star, and is 
Cl1040_12  selected as the WFI counterpart to the X-ray source by the 
Cl1040_12  association algorithm. However, a spectroscopically confirmed cluster
Cl1040_12  member visible farther to the east in the HST image is also within 
Cl1040_12  the 3{sigma} error circle. The X-ray detection has a flux 
Cl1040_12  S0.5-8keV=4.0x10^-14^erg/s/cm2 and HR=0.03, which is consistent with
Cl1040_12  a moderately obscured AGN and unusually hard for stellar X-ray 
Cl1040_12  emission.
Cl1040_23 Source Cl1040_X23 is unambiguously identified with a galaxy ~2'30" 
Cl1040_23  from the cluster centre which is flagged as a possible cluster member
Cl1040_23  based on its photometric properties, though with low membership 
Cl1040_23  probabilities (Pmem~25%). The X-ray flux of the source is 
Cl1040_23  S0.5-8keV=1.1x10^-14^erg/s/cm and HR=0.07, consistent with a 
Cl1040_23  moderately obscured AGN.
Cl1040_67 Source Cl1040_X67 is ambiguously associated with two sources ~4'15" 
Cl1040_67  from the cluster centre. The source farther to the north is extremely
Cl1040_67  faint, whereas the southern source is flagged as a possible cluster 
Cl1040_67  member. The photometry for this source is based on only optical 
Cl1040_67  colours, however, and is therefore considered not reliable. The X-ray
Cl1040_67  flux of the source is S0.5-8keV=3.7x10^-14^erg/s/cm2 and HR=0.03, 
Cl1040_67  consistent with a moderately obscured AGN.
