discov_num notes refcode
RAO 76 A is SB and astrometric binary. Tok2014d
Previously thought to be a binary, but our observations reveal that
it is actually a triple system. The outer component B at 4".8 was
discovered by Robo-AO and confirmed by the 2MASS image and by the new
data presented here. It is located near the low end of the MS. The
main star with astrometric acceleration (Makarov & Kaplan 2005) is Mkr2005
now resolved at 0".4, corresponding to an orbital period of ~100 yr.
The new component Ab is too faint for its detection in the i' band
with Robo-AO. Rbr2015d
RBR 55 Aa,Ab: incorrectly labelled RBR 30 in Table 1 of Roberts et al. Rbr2015d
