Fig. 5
Abundance ratios [Fe/H] i (upper panel) and [Fe/H] ii (lower panel) as a function of Teff for all member stars analysed in M 80 with UVES (blue squares) and GIRAFFE spectra (red circles: setups HR11 and HR13; black crosses: HR11 only; green crosses: HR13 only). Error bars on the right and left side are star-to-star errors for targets observed with UVES and GIRAFFE, respectively.
