The UBV light curves are those of Duerbeck & Yamasaki (1986). The solutions presented are also from that paper, with temperatures estimated from their solutions. Note the inability (also noted in their paper) to fit the V light curves with the same temperature of the secondary (4725 K in V, 4575 K in U & B).
