Final PM decontaminated optical and near-IR CMDs within 3′ of the RR Lyrae rich GCs Minni148 (bottom), 326 (middle), and 330 (top). These decontaminated CMDs show more clearly defined RGB, RC, and HB sequences. RR Lyrae located within 10′ from the cluster centers are also plotted for comparison (red circles). The thin blue lines depict the mean ridge sequences of the known Sgr GCs NGC 6715 ([Fe/H] = −1.49) to the left and Pal 12 ([Fe/H] = −0.85) to the right.
