HRD of our sample (yellow stars) with sources appearing older than 10 Myr in the CMD (CMD−old; see Figure 2) highlighted with green circles. Among these sources, those remaining older than 10 Myr after estimating stellar parameters with FRAPPE (CMD+HRD−old) are marked with dark blue circles. The 0.1, 0.5, 1, 3, 5, 10, and 20 Myr PISA isochrones (Tognelli et al. 2011) are shown as solid black lines, and the 0.2, 0.4, 0.6, and 0.8 M_⊙ mass tracks as dashed grey lines.
