STT 82	Hyades vB 40A. The primary is SB1, P = 4.00 d (Sanford 1921).	San1921
	Primary is SB2, P=4.0002d (Griffin 2012)	Grf2012b
	Also a wider companion (LDS 1166 AC, rho = 62", M = 17.8).
	The 255.5-year binary, ADS 3169 = STT 82 AB is outside our detection
	window, although part of a peak is seen at the edge of the window at
	the expected position angle, according to the orbit in the Worley &
	Heintz (1983) orbit catalog. A wider companion (LDS 1166AC, rho = 62",	Wor1983
	M = 17.8) and the 4d SB are also outside our detection window.	Msn1993a
	A component of pair determined to be a 4.0-d spectroscopic binary.	Grf2012b
