Comparison of the metallicities from the Pristine-Gaia synthetic catalogue with the high-resolution spectroscopic metallicities accumulated by the Pristine collaboration. The photometric metallicities are in very good agreement with their spectroscopic counterparts throughout the metallicity scale, which means that the issues (variable stars, subtly saturated SDSS stars, … ) that led us to erroneously target stars with [Fe/H]_PristineHR > −2.0 as VMP candidates are now resolved. There remains an offset between the photometric and spectroscopic metallicities with the temperature of a star (the color of the dots). Stars with T_eff > 6000 K do tend to have lower photometric metallicities than their spectroscopic metallicities.
