The Gaia renormalized unit weight error (RUWE) is the square root of the normalized χ2 of the astrometric fit to the along-scan observations. Values in excess of about unity are sometimes taken to be a sign of stellar multiplicity.
Abbreviations for “astrometric_excess_noise” and “astrometric_excess_noise_significance” (Lindegren et al. 2021; https://gea.esac.esa.int/archive/documentation/GDR2/Gaia_archive/chap_datamodel/sec_dm_main_tables/ssec_dm_gaia_source.html); these are a measure of “the disagreement, expressed as an angle, between the observations of a source and the best-fitting standard astrometric model.” Values of astr_ex_noise_sig ≳ 2 are considered significant.
