WDS 21353+2812 CHR 103 (HD 205539) : NOTES

discov_num	notes	refcode
CHR 103	A spectroscopic binary, P = 12.2d. Hence triple.
	This system, first announced by McAlister and recalled in a later	McA1984b
	McAlister paper after repeated attempts at confirmation, has been	McA1993
	restored. While perhaps still spurious, the subsequent confirmation or
	suspected duplicity (by another technique) makes the discovery
	measurement somewhat more probable.
