Distributions of the radial velocity differences with respect to the main stellar parameters for the GALAH−GES (top row), APOGEE−GES (middle row), and APOGEE−GALAH (bottom row) common data sets, including dwarfs and giants. Bins containing only one star are in gray in the background; the color-coding (according to the number of stars per bin) starts from two stars. The mean and standard deviation of the differences are also shown in each case. Horizontal axes indicate T_eff (K), metallicity, log g (dex), and v_micro and v_rad (km s⁻¹) from APOGEE DR17 (middle and bottom rows) and from GALAH DR3 (top row).
