WDS 09006+4147 KUI 37 AB : NOTES

discov_num	notes	refcode
KUI 37	10 UMa. Hyad. Well observed RV variation in agreement with the visual
	orbit. Spectral types and masses of components assigned by ten
	Brummelaar et al., based on adaptive optics observations.	TtB2000
	Calculated mass sum is 2.44 +/- 0.12 Msun, consistent with spectral
	types F5V.	Mut2010b
	AB: Additional notes may be found in Duruy (1941),	Dur1941
	Duruy (1942), and	Dur1942b
	Baize (1943).	Baz1943a
	AB: Martin et al. (1998) derive component masses 1.525 +/- 0.104 and
	0.920 +/- 0.080 Msun.	Mig1998
	AB: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 2.37 +/- 0.33, 2.39, and 2.14 Msun, respectively.	Mlk2012
	AB: A typographical error in the Muterspaugh et al. (2010) orbit has	Mut2010b
	been corrected; period is 7961.0d, not 7691.0d. Noticed by Rick Wasson
	(2016, private comm.)
STT 566	AB,C: Optical pair, based on study of relative motion of the
	components using the method of apparent motion parameters.	Kiy2008
	AB,C: Rectilinear solution by Hurowitz et al. (2014).	USN2014a
