Solid lines are the 3σ confidence regions (blue for the primary and red for the secondary) when adjusting the photometry and the flux ratio with Kurucz models. The dot, dashed and dash-dot lines are the confidence region derived from the studies of Smith & Dworetsky (1993), Wahlgren et al. (1994), and Hubrig et al. (1999) respectively. The filled stars are the adopted stellar parameters.
