Comparison of radial velocities from Gaia DR2, that are excluded from EDR3, with radial velocities from RAVE DR6 and LAMOST DR6. Top row: Gaia DR2 radial velocities versus radial velocities from RAVE DR6 (left), colour-coded according to the RAVE DR6 correlation coefficient, and LAMOST DR6 (right), colour-coded according to the separation at epoch 2000. Bottom row: radial velocity differences as a function of Gaia EDR3 G magnitude with the same colour-coding as the top row.
