14.1.6 Radial velocities
While Gaia EDR3 merely repeated the 7 M radial velocities from Gaia DR2, Gaia DR3 introduces 30 M radial velocities using the much larger set of observations.
Tests discussed below show:
Some spurious velocities in the vicinity of bright(er) sources. This is a long known problem that has been greatly diminished in Gaia DR3, but errors of more than 500 may still occur, cf. Section 14.2.6;
A small set of faint magnitude, very red sources still have radial velocities, that may be spurious, cf. Section 14.5.2
