WRH 21 A long-period spectroscopic binary.
1983.3098: Very poor atmospheric conditions. Bag1984a
Torres (2007) incorporates Hipparcos intermediate data with Trr2007b
spectroscopic results to derive orbit. P, e, omega, and T are adopted
from the spectroscopic solution of Scarfe et al. (2007). Resulting Scf2007
masses are 1.38 +0.09/-0.03 and 1.36 +0.07/-0.02 Msun.
