Abstract: We apply the stellar locus method to synthetic $(BP-RP)_{XPSP}$ and $(BP-G)_{XPSP}$ colors derived from corrected Gaia BP/RP (XP) spectra to obtain accurate and precise estimates of metallicity for about 100 million stars in the Milky Way (34 million giants in the color range $0.6 arXiv:2410.19895v1 Announce Type: new
