[X/Fe] vs. [Fe/H] for various intermediate mass elements in the solar neighbourhood: comparison of the average stellar abundances of the model to data of Adibekyan et al. (2013). The data are split into thick disk (green) and thin disk (red) according to the prescription of Adibekyan et al. (2013), in the middle panel of their Fig. 2. The model results are normalised such as the average abundance over all stars of age = 4.5 Gyr that are present today in the solar neighbourhood is solar (see text).
