Fig. 7.
Distribution of ages and metallicities for F2 obtained by fitting 1000 MC samples with the theoretical BaSTI LFs. Upper panel: age distribution. Right panel: metallicity distribution. Central panel: density map of ages and metallicities. Sigma contours are over-plotted in white. Dashed lines show Gaussian fits for ages and metallicities with the values specified in the panels. Accounting for atomic diffusion would reduce the age of the models ∼0.7 − 1 Gyr (see main text).
