MCA 55	Aa,Ab: bet 1 Cyg = bet Cyg A = Albireo = 6 Cyg A. Resolved in 1976 by
	speckle interferometry and has also been seen visually.	McA1982b
	See the discussion of colors and magnitudes of this composite spectrum
	system by Bonneau & Foy (1980).	Bnu1980a
	1977.4816: This object was incorrectly attributed to the system ADS
	12540 = STF 43 by McAlister (1979).	McA1979b
	McAlister & Hendry (1982) also note a distant companion.	McA1982b
	1983.4904: The distant companion reported by McAlister & Hendry (1982)	McA1982b
	would be located beyond our 0".371 ACF window.	Bag1984a
	Spectral types of primary and secondary assigned by ten Brummelaar et
	al., based on adaptive optics observations.	TtB2000
	1998.657: Absolute quadrant determined by triple-correlation technique	Pru2002b
	Aa,Ac: Malkov et al. (2012) derive dynamical and spectroscopic masses
	50.66 +/- 15.18 and 22.40 Msun, respectively.	Mlk2012
	Mk III Limb-darkened diameter 4.834 +/- 0.048 mas.	MkT2003
	NPOI Limb-darkened diameter 4.904 +/- 0.035 mas,
	R = 58.69 (+2.83-3.12 ) \rsun, Teff = 4860 +/- 20 K,
	L = 1734. +/- 174. \lsun.	NOI2023
STFA 43	STTA183.
	AB: B is BD+27@3411, spectrum B8V.
	The physicality of this wide pair has been discussed by Griffin.	Grf1999b
	1995.559: Absolute quadrant determined by triple-correlation technique	Pru2002b
	AB: H 5 5.	MEv2010
	While A & B may share a common origin, it seems virtually certain that	Bst2018
	are not physically associated with each other. The parallax of A is
	9.95+/-0.60 mas while B is 8.38+/-0.17 mas.
RBR 12	Ba,Bb: First resolved in 2002, after multiple non-detections, this is	Rbr2007
	now thought to be a measure of the known Aa,Ab pair MCA 55 with a much	Rbr2013a
	larger than expected position angle error.
