This is the supplementary dataset to Rix et al. (2022), containing Gaia DR3 XP-derived parameters for over one million stars towards the Galactic center.
xp_gc_mh.csv contains XGBOOST-inferred temperatures, surface gravities, and metallicities for 1.5 million stars.
xp_gc_kinematics.csv contains Galactocentric coordinates, actions, and basic orbital parameters for the subset of 1.2 million stars with Gaia DR3 radial velocities.
