 \tablefoot{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 10$^7$ km.}
