Comparison of our metallicities with other Gaia based spectroscopic metallicities such as GSP-Spec pipeline (left) and improved metallicity estimates for VMP stars in GSP-Spec catalogue by M22 (right). The number of stars (with stricter quality cuts), median (μ₅₀), and 1σ standard deviation (σ) in Δ[Fe/H] and median uncertainties on the metallicity measurements (where available) is indicated at the top and bottom of each panel. The dashed lines shows the 1:1 line and corresponding ±0.5 dex offsets.
