Comparison of the photometrically derived metallicities in the PRISTINE DR1 catalog (N. F. Martin et al. 2024) with the spectroscopic metallicity estimates from the MWBP observations of the same stars based on the RVS (left) and SP (right) pipelines as reported in the DESI DR1 Stellar Catalog (S. E. Koposov et al. 2024; DESI Collaboration et al. 2026; S. Koposov et al. 2026). The solid red line in both panels is a 1–1 line, not a fit.
