CHR 51 36 Ser.
This peak was overlooked in the original analysis of our speckle data,
but rediscovered during work on our quadrant determination paper. Hrt1992b
Docobo et al. (2010) derive two possible orbits of this pair. The Doc2010h
preferred orbit yields a dynamic parallax of 15.63 +/- 0.40 mas and a
total mass of 3.82 +/- 0.21 Msun.
