COU2431	Aa: First resolution of primary, which was a known SB (period 112d).
	Metallicity estimates range from -0.78 to -0.14.	Hor2012b
LSC 1	Aa1,2: Docobo et al. (2014) use the spectroscopic elements of Goldberg
	et al. (2002 AJ 124, 1132), together with speckle data and Hipparcos
	parallax, to derive the remaining orbital elements. The resulting
	masses are 1.05 +/- 0.05 and 0.89 +/- 0.05 Msun.	Doc2014h
	Aa1,2: SB2, P=112.56d	Tok2014d
LEP 98	AD: SHY 337. Bayesian analysis by Shaya & Olling (2011) indicates very	Shy2011
	high (near 100%) probability pair is physical.
SEI1363	CR: Also known as BUP 221CR or LDS2480.
NLTT 50309	Combined spectroscopic/astrometric solution, based on high-resolution
	echelle spectra plus archival PTI visibility measurements.
	Derived masses 1.1861 +/- 0.0057 and 0.9407 +/- 0.0049 Msun,
	distance 40.571 +/- 0.052 pc.	Knc2010
	Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
	masses 2.18 +/- 0.15, 2.37, and 1.10 Msun, respectively.	Mlk2012
HDS2989	Da,Db: Previously known as 20582+4011 HDS2989AB, but found to be the D
	component of the CPM pair LEP 98.
	Da,Db: Rectilinear solution by Hartkopf & Mason (2013).	Hrt2013b
