discov_num notes refcode
FIN 318 Aa,Ab: Docobo & Andrade (2013) derive a dynamical parallax of 5.32
+/- 0.20 mas (based on their orbital elements and masses expected from
spectral types) or 4.65 +/- 0.12 mas (based on their elements and
masses given by Tokovinin 2008 MNRAS 389, 925). See paper for
extensive notes on this system. Doc2013d
