Locating CVs in the Gaia low-extinction HRD diagram. Left: Gaia DR3 low-extinction HRD (A₀ < 0.1 mag, parallax uncertainty smaller than 10%, ruwe < 1.4, ). Middle left: Gaia HRD overlaid with Gaia DR3 variability types “CV” (orange circles) and “sdB” (blue triangles). Filled symbols correspond to variability score (best_class_score) > 0.5. Middle right: Gaia HRD overlaid with CVs from the Ritter & Kolb (2003) catalogue with A₀ < 0.1 and parallax uncertainty smaller than 10%. Filled symbols correspond to sources with Gaia DR3 variability detected and symbols with black borders are sources classified as “CV” in Gaia DR3. Yellow stars correspond to CVs removed by the ruwe < 1.4 or criteria. Right: heat map scatter plot of all the epoch photometry data points of the CV variables with best_class_score > 0.5 (all filled orange circles in middle left panel). The Knigge et al. (2011) white dwarf + main sequence star tracks are shown in green.
