Cester1977 - Cester1977U (Johnson U)
The UBV light curves are from Broglia (1964) and the radial velocity curves are from Popper (1957). The solutions are from Cester et al. (1977) with the temperature of the secondary increased from 9410 K to 10700 K to better fit the light curves. The geometrical parameters are from their V light curve solution. The fit to the U light curve is not satisfactory with these parameters as is often the case in black body approximations.
