Notes. For each system, we list the best-fitting isochrone’s age and metallicity, effective temperature of the companion, and predicted distance. Each parameter value is accompanied with a range representing the 16th-to-84th percentile of distribution of ‘accepted’ isochrones (blue points in Fig. 6). RZ Eri is not shown here, as the results would be meaningless (see text for details). Apart from those parameters, for the two SB1 systems we also evaluated stellar masses and radii, which are given in the text.
