AGC 13	tau Cyg = 65 Cyg.A is a Delta Scuti-type variable.
	Spectral types and masses of components assigned by ten Brummelaar et
	al., based on adaptive optics observations.	TtB2000
	Identification of the ascending node is probable although small
	variations of non-orbital origin superimpose on the RV. A is a Delta
	Scuti-type variable. A faint star listed as component F is physical;
	linear formula given by Heintz.
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
	NPOI Limb-darkened diameter 2.169 +/- 0.028 mas,
	R = 4.70 (+/- 0.07 ) \rsun, Teff = 4771 +/- 31 K,
	L = 10.3 +/- 0.2 \lsun.	NOI2023
	AC and AB,D: Optical pair, based on study of relative motion of the
	components using the method of apparent motion parameters.	Kiy2008
	AB: The Soderhjelm (1999) orbit predicts a separation of 0.734", but	Sod1999
	the magnitude difference (published value 2.7mag) may have been too
	great.	Hrt2009
	Calculated mass sum is 2.63 +/- 0.12 Msun. There is some indication of
	a substellar companion orbiting one of the two stars, but this is
	uncertain. This solution uses only a single Keplerian model.	Mut2010b
	AC: Rectilinear solution by Hurowitz et al. (2014).	USN2014b
