[El/Fe] ratio as a function of [Fe/H] for Group 1 stars (filled circles) investigated here and for comparison thin-disc stars analysed in this work, Paper II, and Paper III (open circles). The s-process enhanced star (HD 88446) is marked as an asterisk. Grey dots correspond to the data for the Milky Way thin-disc dwarfs taken from other studies. The Galactic thin-disc chemical evolution model is shown as a solid line (Pagel & Tautvaišienė 1997). Average uncertainties are shown in the box for Zr.
