The 12 new microlensed stars plotted on the α-enhanced isochrones from Demarque et al. (2004). Each set of isochrones have been calculated with the same metallicity and α-enhancement as derived for the stars. In each plot the solid lines represent isochrones with ages of 5, 10, and 15 Gyr (from left to right). Dotted lines are isochrones in steps of 1 Gyr, ranging from 0.1 Gyr to 20 Gyr. Error bars represent the uncertainties in  and log g as given in Table 2. Note that ages reported in Table 3 need not coincide exactly with the ages that may be read off directly from the figures. The age determinations are based on probability distribution functions and is described in Sect. 3.
