Unit-weight uncertainties of parallaxes estimated by deconvolution vs. these uncertainties. From top to bottom, sources with non-zero excess noise (blue), phot_bp_rp_excess_factor larger than 2 (orange), within 10° of the Galactic centre (green), within 3° towards the LMC (red), duplicated sources (violet), all catalogue sources (brown), and QSO (pink). Only sources with more than eight visibility periods and GoF < 5 have been kept in all subsets, except for the subset with non-zero astrometric excess noise, where no GoF upper limit was applied.
