VizieR Online Data Catalog: A2A catalog of 21000 bulge stars from ARGOS survey (Wylie+, 2021)

The A2A survey is obtained by cross-matching the medium resolution spectroscopic survey ARGOS with the high-resolution spectroscopic survey APOGEE DR16. The stellar parameters of the ARGOS stars are recalibrated to the APOGEE stellar parameter scale using the data-driven method The Cannon and a set of training stars observed by both surveys. The table provides revised values of effective temperature, logg, [Fe/H] and [Mg/Fe] with estimated errors, heliocentric radial velocities, as well as photometric information and probability weights for these stars being part of the red clump.
