WDS 22388+4419 HO 295 AB (HD 214608) : NOTES

discov_num	notes	refcode
HO 295	Slight variability is reported.
	Visual sec. is 552d SB2.	Duq1987
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
	AB: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 2.26 +/- 0.16, 2.14, and 1.07 Msun, respectively.	Mlk2012
	AB: For the Horch et al. (2015) combined solution, the spectroscopic	Hor2015
	elements are fixed to those of Duquennoy (1987).	Duq1987
BAG 15	Ba,Bb: There is some confusion in the literature as to whether the
	close Balega pair is Aa,Ab or Ba,Bb. However, Duquennoy (1987) says	Duq1987
	the secondary is a 552d SB2 and Horch et al. (2015) have clearly	Hor2015
	resolved the fainter star into a close pair and derive an orbit using
	the Duquennoy SB elements. The components of the close pair have
	therefore been changed to Ba,Bb accordingly.
	Ba,Bb: For the Horch et al. (2015) combined solution, all elements are
	calculated from the speckle data, but a double-lined orbit exists due
	to Duquennoy (1987). This orbit has similar elements to the orbit here	Duq1987
	except for the time of periastron passage. Assigned spectral types
	for A, Ba, and Bb are F9V, G5V, and K1V; derived masses are 1.12, 0.92
	and 0.77 Msun.	Hor2015
