discov_num notes refcode
A 225 Systemic mass is estimated at 2.6 +/- 1.3 Msun, assuming an Hipparcos
parallax of 7.65 +/- 1.26 mas. According to Heintz (1982), the Hei1982c
computed dynamical mass suggests an evolved pair. Doc2008a
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.47 +/- 1.14, 2.36, and 0.95 Msun, respectively. Mlk2012
