WDS 22280+5742 KR 60 AB (DO Cep) : NOTES

discov_num	notes	refcode
KR 60	B is the flare star DO Cep, which is fairly active with flares of small
	to moderate amplitudes.
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
	AC, AE, AF, and AI: Optical pair, based on study of relative motion of
	the components using the method of apparent motion parameters.	Kiy2008
	AB: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 0.43 +/- 0.06, 0.42, and 0.56 Msun, respectively.	Mlk2012
HZE 5	Heinze et al. (2010) determine the K component is a background object.	Hze2010
FYM 118	The EQ pair was initially listed incorrectly as CQ. The CD pair was
	initially listed incorrectly as a new CT pair.	FyM2014b
