BRG 4 The primary star in the system is a known eclipsing binary with a
period of 0.4455 days (Parihar et al. 2009 MNRAS 395, 593). Since the
angular separation is inside of our inner cut-off, we count the system
as a binary here for the purpose of multiplicity statistics, although
it is really a triple system. To estimate the mass of the primary for
the purpose of deriving the mass ratio to the tertiary component
detected in our images, we use the sum of the masses corresponding to
individual spectral types M1 and M3 derived for the eclipsing binary. Jnn2012
