Mezzetti1980 - Mezzetti1980B (Johnson B)
The B & V light curves are from Johansen et al. (1971). The solutions are from Mezzetti et al. (1980), except that the secondary is constrained to exactly fit its inner Roche surface, and the temperature of the secondary was reduced from 5120 K to 5000 K to better fit the light curves. The radial velocity curve is from Struve (1946) but the orbital phases were shifted by –0.0887 to better represent the circular orbit system. These phase-shifted values were then fitted by least squares to arrive at the velocity semiamplitude of 77.5 km/s and a systemic velocity of +20.9 km/s.
