WDS 21387+2530 CHR 104 (HD 206027) : NOTES

discov_num	notes	refcode
CHR 104	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.
