Notes.Masses are estimated by comparing each object’s brightness in a given filter with the 600 Myr-old BT-Settl isochrone (Allard et al. 2003; Allard 2009) using a distance modulus of 3.33 and assuming no foreground extinction. Boldfaced entries indicate mass ratios derived from the K band photometry of the individual components.
