discov_num	notes	refcode
L 32	Measures from Lewis were assigned to both this pair and	L__1899a
	19590+2953L 31 in the BDS and ADS. Published coordinates and	Bu_1906
	magnitudes are also similar, and only one pair is seen on POSS plates,	A__1932a
	leading to the conclusion that these are the same system. The L 32
	designation was maintained, as its WDS designation was correct.
