Notes. The Chandra cluster flux measurement is also shown. Column 4: XXL cluster flux. Column 5: number of point sources detected by wavdetect within a 60″ radius region around the cluster centre that were not previously detected by XXL. Column 6: total flux of all of the point sources detected by wavdetect within a 60″ region around the cluster centre that were not detected by XXL, with the 1σ lower and upper limits given as error. All fluxes are in the 0.5–2 keV energy band. Column 7: fraction of F60 resolved into point sources by Chandra, as described in Sect. 3.1. Column 8: our assessment of the cluster. Column 9: cluster flux as calculated from Chandra data after point source removal (described in Sect. 3.2) with 1σ errors. XXLIDs marked with (a) appear in Willis et al. (2013) and are therefore part of the XMM-LSS subset of clusters. AGN contamination fractions marked with (b) have possible additional contamination from potential point sources that did not meet our detection threshold (except for XLSSC 634 which has a potentially lower AGN contamination fraction than stated in this table), and contamination values that include these sources are given in Sect. 4. Individual point source fluxes and positions are given in Table A.1.
