WDS 12431+6109 LDS 2320 : NOTES

discov_num	notes	refcode
LDS2320	Originally listed as 10442+6111, based on Luyten's 1950 coordinates,	Luy1970
	but no pair is found at that location. However, a pair in excellent
	agreement with his measure is found at the location of his cross-
	reference catalog entry, BD+61 1312. Apparently there was a 2h error
	in Luyten's 1950 coordinates. Given the size of the error, correction
	to the WDS designation was deemed appropriate.
