WDS 17200-0801 ENG 60 AB : NOTES

discov_num	notes	refcode
CHR 151	Aa,Ab: This newly-discovered pair was unresolved in our earlier survey
	for duplicity among high-velocity stars (Lu et al. 1987). Abt &	McA1987c
	Biggs (1972) list a single radial velocity of -89.3 km/s for this	AbH1972
	object, published in 1950. Additional observations, both by speckle
	and by spectroscopy, are needed for confirmation of its duplicity and
	its high velocity.	Hrt1992b
	B is BD-07@4426.
