A 207 Scardia et al. (2001) orbit preliminary as all the orbital elements Sca2001d
are still rather uncertain. Hipparcos parallax (0".01200 +/- 0.00311)
seems to be overestimated and leads to a mass sum 0f 0.46 Msun,
unacceptable for a system of type F5. Scardia (1982) classified the Sca1982a
star as type F9. Dynamical parallax is 0".0065; the corresponding mass
sum is 2.87 Msun.
