discov_num notes refcode
HU 1443 A,BC is a triple system. We provide the first very tentative orbit for
the outer binary, but note its large residuals from the recent
measures of AB. Strictly speaking, the orbit should describe the
motion of the center-of-gravity of BC around A, rather than the
measures of AB. Such refinement was made for the orbit of A 2592 AB
(17156-0949)}, but it is not warranted for this preliminary orbit. Tok2015c
