Notes. All are available at the XXL Milan database as separate tables: 3XLSSB for the soft band and 3XLSSCD for the hard band. The column name has a prefix when there are two column names given (one with the prefix B and one with the prefix CD). Only the column applicable to the given band appears in the relevant table, but both may show up in the band-merged table 3XLSS. Column names without prefixes are relevant to the individual band only. The last four columns indicate respectively: (X) whether a parameter is computed by XAMIN, in which case the name given in Table 1 of XXL Paper XXIV is listed in the explanation column; (m) whether a parameter is also available in the band-merged table; (o) whether a parameter is present in the multiwavelength table together with those described in Table 11; and (C) whether a parameter is present in the catalogue stored at CDS. (a) Bp1 or CDp1 is set to 1 if the nominal application of the P1 recipe (see Sect. 2.1) is successful in the soft or hard band, respectively. There is a limited number of sources (9 in XXL-N and 9 in XXL-S) band-merged as EP, i.e. extended in the soft and pointlike in the hard band, for which the P1 recipe is successful in the hard band.
