discov_num	notes	refcode
HDS1895	Horch et al (2012) generate two possible orbits, one based on only	Hor2012a
	astrometry, the second "constrained" solution fixes P, T, e, and Omega
	to values determined in a spectroscopic orbit by Torres et al. (2002).	Trr2002
	Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
	masses of 2.27 +/- 0.49, 1.75, and 0.88 Msun, respectively.	Mlk2012
	Ren & Fu (2013) calculated an astrometric orbit, combining Hipparcos
	Intermediate Astrometric Data with spectroscopic elements by
	Latham et al. (2002). They derived component masses 0.93 and 0.42 Msun	Lat2002
	and an estimated semimajor axis of 95.29 mas.	Ren2013
