BU 947	A: bet 1 Sco = 8 Sco A = Acrab. Common proper motion with bet 2 Sco.
	Companion suspected sf on two nights.	B__1963b
H 3 7	H III 7. C is bet 2 Sco and was found as a double in summer 1627 by	C__1627
	Benedetto Castelli. It also has a close interferometeric pair found by
	McAlister.	McA1978b
MCA 42	C: bet 2 Sco = 8 Sco C
	Orbits for two component pairs AB and CE of this complex star system
	were calculated independently of one another by Seymour et al. (2002).	USN2002
bet Sco	Combined spectroscopic/astrometric solution for bet Sco by Holmgren et	Hol1997
	al. (1997) using lunar occultation data; they derive masses, radii,
	distance. There is a typographical error in their Table 4: the value
	of a" is 1.42 mas, not 1.42 arcsec.
	A complex, multi-body solution was not attempted.
