Information on Service 'GDR2AP VAEX HDF5 download'

Further access options are discussed below

We estimated the stellar astrophysical parameters of 120 million stars over the entire sky that have Gaia parallax and photometry from Gaia DR2, 2MASS, and AllWISE. 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.

This resource is not (directly) published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise some caution.
