Malasan1989 - Malasan1989B (Johnson B)

The light curves are from Bookmyer (1985) and the radial velocity curves from Struve (1945). The large scatter in the secondary measurements does not constrain the mass ratio very much and a modern radial velocity curve is needed. The solutions presented are essentially those of Malasan et al. (1989) where I have taken the mean of their two models and set the mass ratio equal to 0.85. The system appears to be overcontact with the obvious presence of a starspot region that was not modeled by them.
