phi And = 42 And. Measure of 1985.830 made by MAPPIT.
Han1987
Scardia et al. (2001) orbit considered preliminary. The real period
Sca2001d
is probably long (>400 yr). The Hipparcos parallax is 0".00443 +/-
0.00080, giving a mass sum of 6.9 Msun, slightly in excess for a
binary of spectral type B7Ve. The dynamical parallax is 0".0033, in
reasonable agreement with the measured one but not acceptable as it
leads to an exaggerated mass sum (16.8 Msun).
Calculated mass sum is 6.5 +/- 2.8 Msun, in reasonable agreement with
spectral types B6IV and B9V, although mass is not well-constrained.
