Kiel diagrams for the MatisseGauguin output parameters (stored in the main DR3 astrophysical parameters table) for high-quality spectra (S/N > 150) and excluding high-rotating stars (vbroadT = vbroadG = vbroadM = 0) and possibly misclassified very cool giants (KMtypestars = 0). The colour codes of the different panels show the stellar density (left panel) and the median of [M/H] and [α/Fe] per point (central and right panels, respectively). The proposed log(g) and [α/Fe] calibrations are applied.
