Notes. This work’s values of ages, and companion’s temperature and metallicity are taken from distribution of the accepted models. Same values for the spectroscopic component come from iSpec (Table 4). Note that the given [M/H] is current, not initial like in Table 5. Literature values of Teff for RZ Eri and SZ Cen are based on colour indices, not spectroscopic analysis. Values assumed by the authors are given with no error, i.e. with “-” in parenthesis.
Values in agreement when Ṗ from Graczyk et al. (2021) is taken into account.
No age uncertainties are given by Ratajczak et al. (2016). Instead two separate solutions are presented.
