Fig. 12
Decontaminated CMDs of the three clusters, with the best-fitting PGPUC isochrones defined in the text overplotted. The zero-age horizontal branch (ZAHB) in all panels of the figure was calculated with the helium abundance Y = 0.245. For VVV CL002, two isochrones at 6.5 Gyr (thick curve) and 8.5 Gyr (dashed curve) are shown.
