Top: star formation rate history of the model. Middle: age-metallicity relation of the model, together with the stellar age and metallicities of the microlensing events of bulge stars from B13. Bottom: the metallicity distribution from the model (thin orange curve) and convolved with a Gaussian of 0.15 dex dispersion (thick orange curve) together with the generalized histograms of the observed MDF in Baade’s Window from Hill et al. (2011, thin dashed red curve) and shifted by −0.21 dex (thick dashed red curve), following the results of Rojas-Arriagada et al. (2014).
