Note: SIM is the quasi-simultaneous solution with just the 1999/2000 data set, REC is the iteratively rectified solution from all observing seasons combined. REC is our preferred solution. Lis the luminosity ratio and RV the radial velocity. The period and the eccentricity were fixed at the values obtained from the orbit.
