Keplerian radii for characteristic Hα emission line velocities (dashed lines) as discussed in the text and labeled as follows; V_w is the maximum extent of the emission in the FSMS data, V_p is the velocity of that double peaked structure, and V_h is the HWHM of the SALT/HRS emission. The solid curves represent the binary separation (labeled a) and the Roche radius of the unseen secondary (Roche₂). The dotted line is the limit imposed by tidal forces, while the dash-dotted line joining stars is the limiting average radius of stable orbits of the outer disk, from Paczynski & Rudak (1980).
