Fig. 4
Abundance ratios [Fe/H] i (upper panel) and [Fe/H] ii (lower panel) as a function of Teff for all analysed stars. Blue squares are stars with UVES spectra; filled circles are those with GIRAFFE spectra, as observed with both HR11 and HR13 gratings, whereas crosses indicate stars observed with only the HR11 (black) or the HR13 (green) grating.
