Fig. 7

Statistical subtraction of host galaxy stellar members from the CMDs of NSC stellar populations. Only a few representative cases are shown. The upper panels show the CMDs in the target region. The CMDs of control field beyond the NSC tidal radius are shown in central panels. The resulting decontaminated CMDs are shown in the lower panels. In each panel we show stellar models from Marigo et al. (2008). The red line is the MS and the RGB, while the blue line is the sequence of core He-burning stars, up to the first AGB thermal pulse.
