Isochrone fitting of our SB2 systems (cf. Fig. 3) with YaPSI isochrones. Each panel corresponds to one system. For each panel, the top subpanel show the giant component (white dot) and the secondary (black dot), the bottom-right and bottom-left subpanels are zoom-ins of the area around the primary and secondary components, respectively. The isochrones are computed for three values of metallicity (see Sect. 3.4).
