Top left: comparison of the Gaia DR3 radial velocities to those of the combined dataset (see text). Top right: same as the top left panel for stars with rv_expected_sig_to_noise ≥ 5. Bottom left: same as the top left panel for stars with rv_expected_sig_to_noise ≥ 10. Bottom right: zoomed-view of the velocity ranges [ − 600, −300] and [300, 600] km s⁻¹ from the top left panel. The stars are represented individually. The blue shaded area delimits a zone of ±15 km s⁻¹ around the main diagonal.
