Distribution of [α/ Fe] vs. [Fe/H] for the 48 stars of Baade’s Window with high quality estimations of Mg, Si, and Ca abundances (red points). The two stars highlighted with blue circles are part of the group of stars identified to have Mg and Si underabundances in Fig. 2. Grey points show the [α/ Fe] vs. [Fe/H] distribution of GES disc stars.
