Comparison between radial velocities from Gaia (V_Gaia) for the targets in this catalogue and those obtained through our spectra (V_HEL). The individual measurements of stars with several measurements in our catalogue are shown as separate points. Top panel: V_Gaia vs. V_HEL. The dashed line indicate the ratio 1:1, while the solid line is the corresponding to the linear regression ([m ± e_m]x + [n ± e_n] = [0.9870 ± 0.0018]x + [5.1 ± 0.3]) regression The error bars are too small to be represented. Bottom panel: V_Gaia vs. V_Gaia − V_HEL. The solid line corresponds to the linear regression indicated in the top panel. The black cross indicates the average error on the data on each axis.
