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.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
