Linnell et al. (1998) used a sophisticated synthetic spectrum light curve program that better represents the data than black body radiation (as used in Binary Maker 3.0). In order to make reasonable fits to their data using BM3, I increased the temperature of the secondary star from 12300 K to 13900 K and decreased the orbital inclination from 85.36 to 84.4 degrees. Limb darkening coefficients appropriate for the temperatures were taken from van Hamme (1993). Note that the U bandpass does not fit the data well, a well-known and common symptom of assuming Planck radiation laws for stars.
