Optical CMDs of Djorg 2, NGC 6401 and NGC 6864. The full photometric catalogues (cluster + field) obtained from our FORS2 pre-imaging are plotted in grey, while blue dots are used for the inner regions (r < 0.5 arcmin). The fiducial loci published by Catelan et al. (2002) for NGC 6864 are over-plotted as a red curve.
