[X/Fe] vs. [Fe/H]. From our investigation of the impact of S/N on the abundances (Paper I, Fig. 2), we conclude that the uncertainties of the abundances are multiplied for S/N< 20. Therefore, we plot our results for the bulge spectra with S/N> 20 using red dots and the results from those with S/N< 20 using pink squares. The solar neighborhood reference sample of giants from Paper I is plotted in gray. Previous abundances for the exact same spectra from Zoccali et al. (2006; oxygen) and Lecureur et al. (2007; magnesium) are plotted using blue diamonds.
