discov_num	notes	refcode
BUP 150	alp Vir = 67 Vir = Spica. A is an Alpha CVn-type variable and
	spectroscopic binary, spectrum B1III-IV+B2V. According to R.G. Aitken,	A__1935f
	this is the fourth binary recognized by spectroscopic methods. It was
	identified as such based on photographic spectra obtained by Prof.
	H.C. Vogel at Potsdam in early 1890. It has been resolved by intensity
	interferometry.
	Intensity Interferometer Limb-darkened diameter 0.87 +/- 0.04 mas.	HBr1974
	AC. Smyth's quoted separation is difference in RA only.	Smy1844
