- Abstract
We produce a clean and well characterised catalogue of nearby objects within 100pc of the Sun from the Gaia early third data release. We characterise the catalogue using the full data release, and comparisons to other catalogues in literature and simulations. We started with a sample of objects with a measured parallax of 8mas. For all candidates we calculate a distance probability function using Bayesian procedures and mock catalogues for the prediction of the priors. For each entry using a random forest classifier we attempt to remove sources with spurious astrometric solutions. >From this paper we provide the following data files: table1c.dat (Table1GCNScat): Any object with a non-zero probability of being within 100 pc and not indicated as a spurious astrometric solutions. We have also included external photometric and radial velocity data, the probability of reliable astrometry, probability to be a white dwarf, the distance 1st, 16th, 50th and 84th percentiles, the positions and velocities in a galactic reference frame. For questions please email richard.smart(at)inaf.it. table1r.dat (Table1GCNSreject): All other entries from the 8mas sample that were rejected as having a zero probability of being inside 100pc or indicated as a spurious astrometric solution. This table has the same format and columns as GCNS_cat.dat. progwd.dat (ProbWDlt05_ProbGFgt05): A catalogue of 45 sources with low probability of being a WD in this work (PWD0.5). For questions please email carrasco(at)fqa.ub.edu. table3.dat (Table3_ResolvedStellarSystems): Resolved binary candidates in the GCNS catalogue as discussed in the section on stellar multiplicity: resolved systems. For questions please email ummi.abbas(at)inaf.it or alessandro.sozzetti(at)inaf.it. maglim.dat (maglimhpx5percentile): The magnitude percentiles for level 5 healpixels used in the luminosity function determinations. For questions please email rybizki(at)mpia.de. distpdf.dat (distance_PDF): The full distance probability density function calculated in section 2 and used throughout the paper. For questions please email rybizki(at)mpia.de. missing.dat (missing_10mas): A list of 1258 objects with published parallaxes greater than 10mas that are not or have no parallax in EDR3. For questions please email celine.reyle(at)obs-besancon.fr. hyacomb.dat (Hyades_ComaBer): A list of 920+212 probable Hyades and ComaBer members in the GCNS sample.
