Notes. (a) Observed rotational velocity. (b) Equatorial velocity for synchronous rotation. (c) Equatorial velocity for pseudo-synchronous rotation. (d) Refers to periastron velocity. (e) Not corrected for interstellar absorption/reddening. Bolometric corrections (BC) by Flower (1996) have been assumed, together with $T_{\rm eff\odot} = 5780$K, $BC_{\odot} = -0.08$, and $M_{bol\odot} = 4.74$.
