Top: (J − K_S) vs. K_S color–magnitude diagram for CL 139 (left) and CL 140 (right). The symbols are the same as in Fig. 2. The best fits are 80 Myr and 1.3 Gyr Padova isochrones (Bressan et al. 2012), respectively. Those isochrones are tied to z = 0.012 and z = 0.008 abundances, accordingly. Bottom: SofI low resolution spectra of Obj 1 and Obj 2 of CL 139 and Obj 1, Obj 2, Obj 3, Obj 4 and Obj 5, of CL 140.
