WDS 19246+5014 BAG 33 (CH Cyg) : NOTES

discov_num	notes	refcode
CH Cyg	Speckle interferometry can clarify the geometry of this symbiotic
	star: adopting a 5750-day period, eccentricity = 0, and distance of
	100 pc, and assuming the total mass of the system is small
	(Wallerstein, 1983 PASP, 95, 564), we obtain rho ~ 0".07. Joint
	speckle interferometric observations with Bonneau and Foy on the 6-m
	telescope in October 1981 also failed to disclose the companion.	Bag1984a
