discov_num	notes	refcode
ES 2322	Espin (1928) gives a measure of the pair now designated DE, with the	Es_1928
	note "Forms distant comes to B.D. +31 4569, which star has at P. 80deg
	an 11.5 nearer, with a 14 mag. S.F." The note is perhaps garbled, as
	there is no obvious companion in this system at an angle of 80deg. The
	value "11.5" was taken as a separation, but is perhaps more likely a
	magnitude. If Espin meant to quote a position angle of 50deg rather
	than 80deg, the 11.5 and 14. mag stars may refer to the pair now
	designated BC.
