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
results, we show that, thanks to Gaia DR2 and the now larger sky
coverage of APOGEE-2 (including APOGEE-South), we obtain an extended
map of the Galactic plane, providing an unprecedented coverage of the
disk close to the Galactic mid-plane (|ZGal|<1kpc) from the Galactic
Centre out to RGal 20 kpc. The improvements in statistics as well as
distance and extinction uncertainties unveil the presence of the bar
in stellar density, as well as the striking chemical duality in the
innermost regions of the disk, now clearly extending to the inner
bulge. We complement this paper with distances and extinctions for
stars in other public released spectroscopic surveys:
324,999 in GALAH DR2, 4,928,715 in LAMOST DR5, 408,894 in RAVE DR6,
and 6,095 in GES DR3.
Description:
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.
