VizieR Online Data Catalog: SHBoost 2024 (Khalatyan+, 2024)
Abstract
We use an xgboost regression to produce a catalogue of stellar properties derived from Gaia DR3 XP spectra, astrometry, and multi-wavelength photometry. This catalogue, referred to as SHBoost, comprises the extinction, effective temperature, surface gravity, [M/H], and mass estimates for more than 217 million stars.
