Near-UV CMD (left panel) and optical CMD (right panel) of 47 Tucanae with the five targets of this study highlighted as blue squares. The 12 Gyr BaSTI (Pietrinferni et al. 2021) isochrone, which reproduces the MS-TO region well, is shown in both CMDs as a red line. The corresponding 40 Myr isochrone, assumed to be representative of the zero-age MS location, is plotted as a solid blue line. The dashed blue lines are the evolutionary tracks that best reproduce the observed positions of the targets in these CMDs.
