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 vsync is the rotational velocity that the star would have in a system with (tidally) synchronized orbital and rotation periods. RRL is the current size of the star’s Roche lobe, whereas Rmax 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 XH . 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 5A 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.
