Comparison of parameters of SB2 systems with isochrone (black line) containing best-fitting model (open square symbols for two components). Age and initial metallicity for the isochrone are given, together with the predicted distance. Measurements and indirect determinations of stellar parameters are marked with filled dots with error bars, and their associated models are marked with open squares. Components labelled ‘spectroscopic’ are represented with orange symbols, while the ‘companions’ are shown with light blue ones. For each object, we show M − R, l_comp/l_spec − R, M − T_eff, and l_comp/l_spec − T_eff panels. On the l_comp/l_spec panels, the isochrones were scaled with respect to the absolute magnitude of the model that matches the ‘spectroscopic’ component; thus, it is by definition located on the grey dashed line that marks the unity. In cases where a certain parameter was not used as a constraint in the fitting process (e.g. R_comp for AL Ari or l_comp/l_spec for SZ Cen), its model values from all the accepted isochrones are shown with grey dots. Zoomed-in images of the vicinity of the determined parameters were drawn for clarity in the insets. Here, we show results for AL Ari and A084011, while other systems are presented in Fig. A.3.
