discov_num notes refcode
A 2329 Using the Hipparcos parallax value of 60.22 +/- 1.75 mas, the orbital
elements of Andrade (2007) yield a mass sum of 1.25 +/- 0.14 Msun. Ana2007
Masses of the two K7V components are estimated at 0.63 +/- 0.01 and
0.62 +/- 0.01 Msun.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.37 +/- 0.12, 1.25, and 0.65 Msun, respectively. Mlk2012
