Top: dependency of the components’ masses (red: primary dashed lines show the error range, blue: secondary) on the orbital velocity of the secondary (for K_pri = 40.15 km s^-1, Müller et al. 2010). The light blue horizontal region indicates the hydrogen-burning mass limit (Chabrier & Baraffe 1997). The green thick line shows our determination of K_sec = 232.9 km s^-1. The error range is indicated by the green dashed lines.
