Number of hot stars (log scale) with radial velocities in DR3, split up according to rv_template_teff, grvs_mag (left panel) and G magnitude (phot_g_mean_mag) (right panel). Each sub-panel lists the magnitude range and the number of stars within that range. While DR3 has a formal cutoff of magnitude 12, there are some stars fainter than this because of the difference between G_RVS and grvs_mag (see Sect. 3).
