Fig. 7

Mass versus age for the cluster candidates in the two PRGs, NGC 3808 (top), and NGC 4650A (bottom). Red squares are for NGC 3808A objects and blue circles for NGC 3808B. The completeness curves at 50% and 90% for the V- and B-bands are shown with dashed and dotted lines, respectively. Vertical lines show the age bins used to estimate the SFR; see Sect. 3.4.
