Abstract:We combine high-resolution spectroscopic data from APOGEE-2 survey Data Release 16 (DR16) with broad-band photometric data from several sources, as well as parallaxes from Gaia Data Release 2 (DR2). Using the Bayesian isochrone-fitting code StarHorse, we derive distances, extinctions and astrophysical parameters for around 388,815 APOGEE stars, achieving typical distance uncertainties of 6% for APOGEE giants, 2% for APOGEE dwarfs, as well as extinction uncertainties of 0.07mag when all photometric information is available, and 0.17mag if optical photometry is missing. StarHorse uncertainties vary with the input spectroscopic catalogue, with the available photometry, and with the parallax uncertainties. To illustrate the impact of our ...(more)

The five catalogues (APOGEE DR16, GALAH DR2, GES DR3, LAMOST DR5 and RAVE DR6) contains distances, extinctions, temperatures, metallicities and masses derived by the spectroscopic-astrometric-photometric StarHorse Bayesian code. The files also contain the stars Galactic position and the ID of the corresponding spectroscopic survey and Gaia ID used in the calculations as well as flags indicating the quality of the derived quantities. The calculation, the code and the main results of these catalogues are explained detailed in the paper entitled above.
