WDS 20429-1856 WOR 41 : NOTES

discov_num	notes	refcode
WOR 41	Worley (1989) measures were originally listed as confirmations of	Wor1989
	Kuiper's 1943 observation of 20429-1857 KUI 100AB. However, the A comp	Kui1943
	of KUI 100 has very high proper motion; separation and angle in 1978
	would be very different. We assume that Worley measured this pair near
	KUI 100; the separation and angle agree, but Worley's magnitude
	difference estimates are rather different.
