Comparison between derived [Mg/Fe] abundances in this work and those provided from Gaia DR3 data. Top row: abundance ratios [Mg/Fe] vs. [Fe/H] from X-shooter (top-left), Gaia DR3 (top-middle), and both catalogues together (top-right, Gaia DR3 data are represented by green crosses), colour-coded by the stellar effective temperature in the first two panels. The red line is the same as Fig. 5. Bottom row: stellar abundance difference between catalogues as a function of the effective temperature (bottom-left), surface gravity (bottom-middle), and metallicity (bottom-right), colour-coded by the measured [Mg/Fe] abundance. The offset estimates are the same as those described in Fig. 1.
