Consistency between astrometric values in DR2 and EDR3. The histograms show the differences in parallax and proper motion normalised to the errors , where x is ϖ, μ_α * or μ_δ, and compared to a Gaussian distribution with 0 mean and variance of 1. The differences in μ_α * are due to a systematic in DR2 that has been now corrected. We have corrected the parallaxes (Eq. (3)) using the median offset for DR2 (−27 μas) and for EDR3 (−17μas).
