STF 113 42 Cet.
AB: Absolute quadrant for 1998.657 determined by triple-correlation
techniques. Pru2002b
A,BC. 1985.8430: This autocorrelogram was remeasured; the new results
are listed in catalog.
Star A (mag. 6.3, G8III) is in slow direct motion at 1.6" separation.
T incorrectly given as 1992.52 by Baize (1990); should be 1993.02 Baz1990a
(erratum noted in Inf. Circ. 111, 1990)
FIN 337 BC: 1982.7629, 1982.7657, 1983.7106: A mistake in reduction resulted in
90 degree errors for these three measures. McA1987b
BC: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.79 +/- 0.56, 3.32, and 1.20 Msun, respectively. Mlk2012
