Stellar Loci. VIII. Photometric Metallicities for 100 Million Stars Based on Synthetic Gaia Colors
Bowen Huang, Haibo Yuan, Shuai Xu +4
We apply the stellar locus method to synthetic and colors derived from corrected Gaia BP/RP (XP) spectra to obtain precise estimates of metallicity…

A Spatial Uniformity Check of Gaia DR3 Photometry and BP/RP Spectra
Bowen Huang, Haibo Yuan, Kai Xiao
Gaia DR3 photometry and BP/RP spectra have been widely used as reference in photometric calibrations. In this work, we check the spatial uniformity of Gaia DR3 photometry and BP/RP…
