discov_num notes refcode
STT 4 Hipparcos parallax of 0".01115 yields a mass sum of 2.75 Msun
with an uncertainty of 38% overestimated for a double star of
spectral type G0. Dynamic parallax is 0".0108, agreeing well with
the measured parallax. Sca2000b
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.72 +/- 0.59, 2.35, and 1.05 Msun, respectively. Mlk2012
