Parameters of 220 million stars from Gaia BP/RP spectra
Description
We present parameters of 220 million stars, based on Gaia XP spectra and near-infrared photometry from 2MASS and WISE. Instead of using ab initio stellar models, we develop a data-driven model of Gaia XP spectra as a function of the stellar parameters, with a few straightforward built-in physical assumptions. Here, we provide the resulting catalog of stellar parameters, our trained stellar model, and a few Python scripts that demonstrate how to interact with the catalog and model.
See the README.md for more information.
