BU 1015 Hipparcos parallax of 0".00883 yields a mass sum of 2.87 Msun
with an uncertainty of 75% slightly in excess for a binary of
spectral type F5. The great uncertainty concerning the sum of
masses is largely due to the consistent error in the measured
parallax. The dynamical parallax is 0".0085, agreeing well with
the observed parallax. Sca2000b
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.44 +/- 1.04, 2.58, and 1.20 Msun, respectively. Mlk2012
