Abundance trends for our clean subsample of stars for all elements of our analysis. The data are tagged into two groups called thin (blue dots) and thick disc (red triangles), according to the dividing line in [Mg i/M] of Fig. 2. The error bars in the lower right corner of each panel indicate the typical error over the sample: the smaller error bar is the median error over the whole clean subsample, the larger error bar the median error over abundances derived from spectra with S/N< 25 in HR10. The clean subsample of Cr i, Ni i, and Y ii is restricted to S/N> 40.
