Comparison of the CMDs of VV124 in different (elliptical) radial annuli with the RGB ridge lines for the Galactic globular clusters NGC 6341, NGC 6752 and NGC 104 (from left to right), from the set by Bedin et al. (2005), that provides the templates in the same ACS-WFC VEGAMAG system as our observations. The reddening, distance moduli and metallicities of the clusters are taken from Ferraro et al. (1999), as in Paper I. In the right panel the ridge lines are labeled with the [M/H] value of the corresponding cluster in the Carretta & Gratton (1997) scale (Col. 4 of Table 2 of Ferraro et al. 1999). The radial range of the left panel coincides with the innermost radial range considered in Paper I.
