[Zn/Fe] vs. [Fe/H]. Symbols: present work (filled red circles), Barbuy et al. (2015; green filled triangles), Ishigaki et al. (2013; blue filled circles), Howes et al. (2015; green open circles), Howes et al. (2016; green crosses), Casey & Schlaufman (2015; grey filled circles), Koch et al. (2016; black open squares), Bensby et al. (2017; black filled circles). Chemical evolution models by Kobayashi et al. (2006; red dotted line). The Barbuy et al. (2015) models are shown for enrichment timescales of 2 (black) and 3 (blue) Gyr. In each case, the models for radius with respect to the Galactic centre of r < 0.5 kpc (dashed lines), 0.5 <r < 1 kpc (dotted lines), 1 <r < 2 kpc (dashe-dotted lines), 2 <r < 3 kpc (long-dashed lines) are overplotted. Errors are assumed as in Fig. 7.
