Giuricin1981 - Giuricin1981V (Johnson V)
The B & V light curves are normal points given in Schultz & Walter (1977). The solutions presented are from Giuricin et al. (1981). The largest radius of the larger, cooler star (the one filling its Roche surface) was decreased slightly to make it physically reasonable for a semi-detached system. The radii given in Giuricin et al. (1981) for the “a” radii are too large to fit within the Roche surface for their given mass ratio. Also, the temperature of the cooler star was reduced from 4470 K to 3975 K in order to better fit the light curves.
