BU 4 See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
The Hipparcos parallax (0".00616 +/- 0.00141) yields a mass sum of Sca2001d
4.7 Msun, in excess for a binary of type F1III.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 9.73 +/- 6.50, 3.62, and 1.64 Msun, respectively. Mlk2012
