Notes. The line separates samples that use the SDSS (lower part) from samples that do not (upper part). The columns correspond to: (1) name of the catalogue; (2) number of galaxy systems in the original catalogue; (3) number of (central) galaxies in common with our primary sample (sample of candidates before applying the isolation criteria); (4) number of (central) galaxies found in the SIG, SIP, or SIT catalogues; (5) percentage with respect to the galaxies in common to the fourth column.
