WDS 17569+1811 J 1352 : NOTES

discov_num	notes	refcode
J 1352	Jonckheere notes ADS positions are 1970 and 1920. In his 1952 paper
	he uses 1950 ADS position and has a note "two couples?". There is
	indeed a measure that indeed looks different:
	1951.62, 39.9@, 3.33", 11.3-11.3.	J__1952
	Observations incompatible. Is there confusion between different pairs,
	as thought by Jonckheere (JO 35, p 53)?	Cou1952b
