Distribution of the main Gaia DR3 variable classes, as defined by Gavras et al. (2023), in the variability space of Figure 8 used to define P_var. All panels show the distribution of the variables identified in Gaia DR3 (phot_variable_flaց = ’VARIABLE’) in gray and the density distribution of a given class of variables, as labeled in each panel. We only show classes with at least 5,000 identified sources and we overlay our P_var = 0.3 threshold for comparison. The proposed cut effectively rejects the most obvious classes of variables.
