orbital velocity in "/binary/private/binary_wind.f90"

[astro-sjgao]

At line 118 of "/binary/private/binary_wind.f90", only b%m(s_i) is taken into account. However, in Hurley et al 2002 eq. 8, the orbital velocity is $v_{\rm orb}^2=\frac{GM_{\rm b}}{a}$, where $M_{\rm b}$ is the total mass of the binary (eq. 5 in Hurley et al. 2002), and $a$ is the orbital separation.

Is there a small mistake?
