Ratio of the numerically estimated mass transfer rate $\dot{\stackrel{\sim }{M}}$ in the presence of the Coriolis force to the analytic estimates ${\dot{\stackrel{\sim }{M}}}_{\mathrm{analytic}}$ (Eq. (A.25) for for the adiabatic case (left) and Eq. (A.30) for the isothermal case (right)). The solid curves following the dots indicate the fitting formulae given in Eq. (A.2). The solid vertical gray lines indicate equal-mass binary. Note that no assumption for the overfilling factor is made for this comparison as the overfilling factor is a scaling factor (see Eqs. (A.25) and (A.30)). We refer to Fig. 9 for a comparison of $\dot{\stackrel{\sim }{M}}$ between L_in and L_out for a given overfilling factor.
