discov_num notes refcode
CHR 86 Aa,Ab: This system, first announced by McAlister and recalled in a McA1984b
later McAlister paper after repeated attempts at confirmation, has McA1993
been restored. While perhaps still spurious, the subsequent
confirmation or suspected duplicity (by another technique) makes the
discovery measurement somewhat more probable.
STT 589 AB: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
