Notes. The quantity r is the radius at which the orbital disk speed is 700 km s^-1; $M_{\rm X}$ the mass of the compact object. $a_{\rm r}$ is the upper limit to the radius of the companion for the red side of the disk to be visible on JD +307.5; $a_{\rm b}$ for the blue. $M_{\rm S}$ is the mass of the system, masses in units of $M_\odot$ . The binary separation A is in units of 10⁷ km.
