Abundance-scaling relations of Gaia DR3 GSP-Spec and APOGEE DR17 ASCAP abundances for a sample of 2450 red clump stars in common. Left: offset between Gaia DR3 mh_gspspec metallicities and APOGEE DR17 ASCAP [M/H]. Right: offset between [α/Fe] (from GSP-Spec) and [Ca/Fe] (from APOGEE). In both panels, the dashed line indicates the correction we applied to calibrate Gaia on the APOGEE scale, given in Eqs. (4) and (5).
