Gaia BPRP CMD displaying members of the 12 stellar clusters that have matches with USco members from F17. The blue dots are all sources in the 12 SigMA clusters that pass additional photometric quality criteria (see text). The red dots indicate sources that are both in SigMA and F17. Two PARSEC isochrones are shown for 5 Myr (solid) and 10 Myr (dashed), marking the earlier assumed nominal ages of USco. The arrow shows an extinction vector with a length of A_G = 1 mag. See Fig. C.6 for an overview of the separate CMDs of the individual 12 clusters.
