We provide estimates of log age, log mass, log temperature, log luminosity, log surface gravity, distance modulus, dust extinction (A0), and average grain size (R0) along the lines of sight. In contrast with other catalogs, we do not use a Galactic model as prior but weakly informative ones. Our estimate and uncertainties are quantiles, so they are invariant under monotonic transformations (e.g., log, exp). This means that one can use our median estimate to obtain the median distance or temperature, for instance, and likewise for the uncertainties.2022arXiv220103252Fhttp://dc.g-vo.org/gdr2ap/q/download/infoCatalogResearchGaia0/0-1157174 571741.986e-19 4.966e-19http://dc.g-vo.org/gdr2ap/q/download/coverageOptical
