discov_num notes refcode
STF 183 According to Scardia et al. (2001), orbital elements are well defined; Sca2001d
only the period is still rather uncertain. The Hipparcos parallax
(0".00727 +/- 0.00189) gives a mass sum of 3.8 Msun +/- 82%, in excess
for a binary of type F2. The dynamical parallax (0".0074) agrees well
with the observed one.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 4.82 +/- 2.85, 3.45, and 1.35 Msun, respectively. Mlk2012
