Caption: Figure 11.

Two-dimensional histogram of metallicity for the crossmatched VMP sample (∼500 stars), comparing the model-predicted [Fe/H]model (x-axis) with the metallicity [Fe/H]GaiaXP derived by L. Yang et al. (2025) from Gaia XP spectra (y-axis). Color indicates the number of stars in each bin, and the red dashed line shows the one-to-one relation (y = x).
