Hertzsprung-Russell diagrams for the microlensed dwarf sample, split into six metallicity bins (as indicated in the plots). In each subplot one set of isochrones is shown (with ages 1, 5, 10, and 15 Gyr delineated), representing the mean metallicity in the range indicated. The isochrones are calculated with the α-enhanced Yonsei-Yale models from Demarque et al. (2004). The stars have been colour-coded according to their metallicity (as shown by the colour bar on the right-hand side). MOA-2014-BLG-131S (mb14131) has been identified in the [Fe/H] > 0 subplot on the lower right-hand side. OGLE-2013-BLG-0911 that is excluded from the final bulge sample (see Sect. 4) is marked by a yellow circle.
