Upper panel: difference in [Mg/Fe] found for the UVES red clump (open circle) and RGB stars (full circle) with the old and new sets of parameters as a function of the new metallicities. The black line shows the mean value of this difference ( − 0.06) and the two dotted lines the  ± 1σ dispersion (σ = 0.10). Lower panel: [Mg/Fe] in the UVES bulge stars (red points, computed with the new stellar parameters) compared with the [Mg/Fe] in the thin (black squares) and thick (blue triangles) discs stars from Bensby et al. (2004, 2005), Reddy et al. (2006).
