Notes. Each element gives the number of sources with different classifications between any two modules, expressed as a fraction of the number of sources in common between those two tables. Sources labelled unclassified in https://gea.esac.esa.int/archive/documentation/GDR3/Gaia_archive/chap_datamodel/sec_dm_extra--galactic_tables/ssec_dm_qso_candidates.html#qso_candidates-classlabel_dsc and https://gea.esac.esa.int/archive/documentation/GDR3/Gaia_archive/chap_datamodel/sec_dm_extra--galactic_tables/ssec_dm_qso_candidates.html#qso_candidates-classlabel_dsc_join are excluded. The columns list all the modules that provide classifications. The rows list all modules that add sources to the table: the last four of these are not classifiers, but provide sources based on other labels.
