[El/Fe] ratio as a function of [Fe/H] in the investigated stars of Group 2 (filled circles) and Group 3 (thick squares, Papers I and II). The data for the Milky Way thick-disc stars were taken from Mishenina et al. (2013, triangles), Mashonkina et al. (2007, crosses), Reddy et al. (2006, squares), and Bensby et al. (2005, stars). The averaged values for alpha-elements consist of Mg, Si, and Ca abundances.
