Notes. In the first rows we show the median uncertainties (first three numerical columns) and upper limit uncertainty for 80% of stars (three columns from the right) for stars in the AC20-ϖ∕σϖ > 3 sample for DR2 (first row), for the stars from EDR3 in common with DR2 (using the gaiaedr3.dr2_neighbourhood table for the correspondence between sources), and for EDR3. The last rows compare the heliocentric velocity uncertainties in DR2 and EDR3 for the sample with 6D velocities (6dsample) when the error in vlos is not (left) and is considered (right).
