Notes. Spectral types are taken from Sota et al. (2011) and Sana et al. (in prep.) or are our own determinations (the stars highlighted by italics). Projected rotational velocities that do (vsini (FT+GOF)) and do not (vsini (PF)) account for extra broadening; ΘRT – extra broadening velocities derived by assuming a radial-tangential distribution of photospheric turbulence; – initial evolutionary masses determined from the tracks by Brott et al. (2011), with initial rotational velocities of ~300 km s-1. Uncertainties for : +25/−37% for the higher and +12/−20% for the lower mass end, respectively; for Teff: ±500 to 1500 K, and for log g : +0.2/−0.1 dex.
