Comparison of the four isochrones used to determine stellar masses. For all shown isochrones, solar metallicity, a distance to the cluster of 8 kpc and a foreground extinction of AKs = 2.35 mag is adopted. As in Figs. 9 and 10, the dotted lines enframe regions in the CMD with ambiguous mass assignments (shaded in grey) and the initial masses are labelled along the isochrones.
