Abundance ratios [X/Fe] vs. [Fe/H] in member stars of clusters (large filled circles – in blue for clusters with R_GC < 6.5 kpc, in green for clusters with 6.5 kpc < R_GC < 9.5 kpc, and in violet for clusters with R_GC > 9.5 kpc), in thin-disc stars (small grey squares) and in thick-disc stars (small black triangles). The blue dashed lines represent the solar values. The red dash-dotted line is the relationship of Adibekyan et al. (2011) which separates thin- and thick-disc stars.
