Accounting of the 550 737 unique variable sources published in DR2. All have an entry in the Gaia archive gaia_source and vari_time_series_statistics tables. Their distributions in the additional variability tables are shown. The classification output types are mutually exclusive so that their sum matches the total number of entries in the published vari_classifier_result table. Eighty sources appear in more than one SOS table (not illustrated), which is detailed in Sect. 4.5. The overlap between similar-type classification and SOS is detailed in a Venn-like fashion showing the counts in the three possible subsets. A few hundred sources have different assigned types in classification and SOS tables (not illustrated), as explained in Sect. 4.6, hence the difference on the left between the total type count and the unique source_id count. No SOS module treated δ Scuti & SX Phoenicis stars.
