Panela: [Zn/Fe] vs. [Fe/H]: same as in Fig. 4, including the damped Lyman-alpha systems data by Rafelski et al. (2012). Models from FB17 are overplotted (same details as in Fig. 4); panel b: [α/Fe] vs. [Fe/H]: data by Rafelski et al. (2012), [O/Fe] in DLAs by Cooke et al. (2015) and present results for [O/Fe] in the sample stars. The model lines in panel a: correspond to the same Galactic bulge radii as in Fig. 4. A typical error bar is indicated in the right upper corner in both panels: for [Zn/Fe] it corresponds to a mean value of the two reference stars given in Table 4. For [α/Fe] the error is of ±0.10 for both thestars and DLAs.
