WDS 00568+6022 BU 1099 AB : NOTES

discov_num	notes	refcode
BU 1099	Theta for 1979.7703 incorrectly given as 308.6 in McAlister & Hendry	McA1982d
	(1982). Also, the measure for 1979.7730 was a spurious preliminary
	measure of the observation on 1979.7703, and has been deleted.
	The A component is the D component of 00567+6043.	Mam2017
BAG 10	Aa,Ab: The primary is 4.24d SB2 (Young, Pub DAO Victoria 1, 287, 1921;
	F.C. Fekel, personal comm.). HR 266.
	Astrometric binary (P=4.85yr) discovered in residuals to speckle
	data for 83-year AB pair (Cole et al. 1992), as well as in residuals	CWA1992
	to SB orbit.
	The Ab component is a 4.2d pair consisting of a B9V and A7V.	Tok2021b
