CMDs obtained from HST/ACS F435W and F606W images. Two young clusters and the background field for B048-S112 are shown. Isochrones for a range of ages at supersolar metallicity come from Cioni et al. (2006a, 2006b). The inset legend lists the isochrone ages shown, in log years. A distance modulus of 24.43 and reddenings of 0.25 mag have been assumed in positioning the isochrones. Median photometric errors at the five indicated magnitudes are shown in the middle panel, but refer to all three panels. From these diagrams, we have derived an age of 0.35 Gyr (log age = 8.55) for B049-G112, and 0.25 Gyr (8.4) for B458-D049.
