discov_num notes refcode
YSC 67 AB + TOK 420Aa,Ab: The neglected pair YSC 67 turned out to be a new
triple. The outer 0".35 binary AB was known previously, now we detect
elongation that implies an inner subsystem Aa,Ab. We compared with
stars in the same area of the sky observed before and after to assure
that the elongation is not of instrumental origin; it is seen in two
filters. Tok2015c
