DR2 variability processing overview. Data were published from the highlighted yellow boxes for the validation filtered sources. There were two main tracks: one starting from ≥ 2 G-band FoV transits (left panel), and the other from ≥20 G-band FoV transits (right panel). The former resulted in the published nTransits:2+ classifier in the vari_classifier_result table, and the latter resulted in the published SOS tables of vari_short_timescale and vari_rotation_modulation. The published SOS tables of vari_rrlyrae, vari_cepheid and vari_long_period_variable result from a mixed feed of the published nTransits:2+ classifier (for sources with at least ≥ 12 G-band FoV transits) and from the unpublished classifier of the ≥20 FoV track.
