STTA 45	AB: H VI 98. A is V774 Tau. B is BD+05@613, and a suspected variable.
	AB: SHY 21. Bayesian analysis by Shaya & Olling (2011) indicates very	Shy2011
	high (near 100%) probability pair is physical.
	AB: H 6 98.	MEv2010
	Toyota et al. (2009) monitored the RV of both the A and B components
	every 1-2 months between 2003 Mar - 2007 Nov, using a high-dispersion
	echelle (precision ~10 m/s). Standard deviations of the RVs of both
	components are <40 m/s and velocities show no periodic variation.
	These results rejects the association of a planet of mass > 1.8 Mjup
	with either star.	Toy2009
