Abundance ratios vs. atomic numbers of the idr2/3 stars in the solar neighbourhood and in the inner disc/bulge (selected in the [Fe/H] range from −0.10 to +0.33 dex, i.e. including the metallicity ranges of the four clusters) compared with the chemical pattern of NGC 6705, Trumpler 20, NGC 4815, and Be 81. The continuous lines mark the solar abundances, and the shaded area the 1σ region with σ = 0.1 dex.
