Note that this *cannot* be matched against the DR1 or DR2 source_ids.meta.id;meta.mainlongindexedprimaryfidelity_v2A probability that eDR3 has a good astrometric solution for this source, with values between 0 (meaning likely spurious solution) and 1 (meaning likely good solution). This is the published probability estimate.stat.fitfloatindexednullabletheta_arcsec_worst_sourceDistance to the eDR3 source within 30 arcsec of the object for which ΔG-θ is maximal. See norm_dg for details.arcsecpos.angDistancefloatnullablenorm_dgThis is a heuristic measure for contamination by bright stars in the neighbourhood. It is computed as ΔG-θ, where θ is the distance to another Gaia eDR3 object in arcsec (reported in theta_arcsec_worst_source), and ΔG is the magnitude difference in mag. This column gives the maximum of the values for all eDR3 sources within 30 arcsecs of the object.instr.backgroundfloatnullabledist_nearest_neighbor_at_least_m2_brighterDistance to the nearest neighbour in gaia_source at least 2 m fainter than this source.arcsecpos.angDistancefloatnullabledist_nearest_neighbor_at_least_0_brighterDistance to the nearest neighbour in gaia_source at least as bright as this source.arcsecpos.angDistancefloatnullabledist_nearest_neighbor_at_least_2_brighterDistance to the nearest neighbour in gaia_source at least 2 m brighter than this source.arcsecpos.angDistancefloatnullabledist_nearest_neighbor_at_least_4_brighterDistance to the nearest neighbour in gaia_source at least 4 m brighter than this source.arcsecpos.angDistancefloatnullabledist_nearest_neighbor_at_least_6_brighterDistance to the nearest neighbour in gaia_source at least 6 m brighter than this source.arcsecpos.angDistancefloatnullabledist_nearest_neighbor_at_least_10_brighterDistance to the nearest neighbour in gaia_source at least 10 m brighter than this source.arcsecpos.angDistancefloatnullablefidelity_v1A probablity that eDR3 has a good astrometric solution for this source, with values between 0 (meaning likely spurious solution) and 1 (meaning likely good solution).
