Notes. For each object we display the initial mass and initial rotation velocity of the best-fitting models and we compare the observed values (Shenar et al. 2016) of the fit parameters to their model values at the moment the best fit is achieved. The parameter v_sync is the rotational velocity that the star would have in a system with (tidally) synchronized orbital and rotation periods. R_RL is the current size of the star’s Roche lobe, whereas R_max is the maximum radius of the models at any point in time before the best fit is achieved. is the lowest χ² value achieved with our three fit parameters T_*, log L and X_H . Unlike in Table D.1, we do not consider the model rotation velocities since these objects do not have observed constraints on the rotation velocity (except SMC AB 5_A with v sin i < 300 km s−1). In this table, only binary stars are considered and compared to models that are core hydrogen burning.
