discov_num notes refcode
LAB 4 sig Her = 35 Her. Double-lined spectrum.
1972.28, 1973.45: Two of the three observations yielded fringes in the
Fourier transform which were quite different; this is difficult to
reconcile with the 50-yr period estimated from Kepler's law. Lab1974
This object was misidentified as tau Her by McAlister (1978). The McA1978c
observation on 1976.2963 which was reported there as yielding a
negative result does indeed show duplicity, as was correctly reported
by McAlister later that year. The negative result reported in the McA1978b
earlier paper for 1976.2991 is spurious.
1977.1781: This is a previously unpublished photographic measure.
1977.3284: Theta incorrectly given as 5.7 deg by McAlister & Hendry McA1982b
(1982); correct value published by McAlister et al. (1989) McA1989
1983.3098: Very poor atmospheric conditions. Bag1984a
Measure of 1988.258 made by MAPPIT. Naj1989
Martin et al. (1998) derive component masses 3.036 +/- 0.714 and
1.498 +/- 0.519 Msun. Mig1998
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 6.05 +/- 1.14, 6.07, and 2.57 Msun, respectively. Mlk2012
