Minimum masses, ℳ sin³ i, for the primary and secondary components of the SB2 binaries (squares). The magnitudes on the top and right axes are computed according to the ℳ–M_Ks relation in Benedict et al. (2016). Lines of constant mass ratio values are shown as dotted diagonals. Dashed contours correspond to the same total flux for pairs M_Ks, 1 and M_Ks, 2. The arrows point to the estimated absolute masses and magnitude M_Ks. Long arrows are indicative of low orbital inclinations.
