DAE 3	RBS 887
	Daemgen et al. (2007) derive distance of 19.6 +/- 4.6 pc, separations
	of 20.8 +/- 6.0 au (AB) and 3.7 +/- 1.1 au (BC), and predicted orbital
	periods of 157 +97/-93 yr (AB) and 16 +10/-9 yr (BC). Spectral types
	for the three components are M3.5 +/- 0.5, M4.5 +/- 0.5, and M4.5 +/-
	0.5; masses 0.29 +0.11/-0.08, 0.16 +0.05/-0.04, 0.16 +0.05/-0.0 Msun.	Dae2007
	2MASS J10364483+1521394 is a triple in the Ursa Major moving group,
	consisting of a low-mass M dwarf orbited by 2 less-massive companions.
	Calissendorff et al. (2017) derive orbits for the BC pair, as well as
	A,BC. The semimajor axis for BC is 161 +/- 2 AU; combined mass for the
	pair is 0.482 +/- 0.145 Msun. If the BC dynamical mass is constrained
	to this value, an orbital solution for A,BC yields a semimajor axis of
	38 +/- 4A U and a system mass of 1.00 +/- 0.03 Msun for the triple.
	The mass of A is 0.53 +/- 0.20 Msun, while B and C have similar masses
	of 0.24 +/- 0.07 Msun each.	Jnn2017b
