Robust Data-driven Metallicities for 120 Million Stars from Gaia XP Spectra

This is the dataset accompanying Andrae et al (2023), "Robust Data-driven Metallicities for 120 Million Stars from Gaia XP Spectra".

Table 1 (124,060,658 rows) contains XGBoost parameters (temperature, surface gravity, and metallicity) for all stars in the sample. 

Table 2 (13,300,628 rows) contains Gaia DR3 parameters and XGBoost parameters for a vetted sample of RGB stars with reliable measurements. 

The tables are provided in FITS and CSV formats, and the full data model is described in the accompanying paper.
