HU 280 Distance in measure given by ADS for 1908.2 (6n, Bry) needs correction.
It represents two annual means: 0.18" in 1907 and 0.30" in 1908; the
latter includes values 0.52", 0.19", 0.18", the first of which must be
rejected, the observer having even noted in addition "not separated".
The same kind of error exists for some other objects on the same night
(BU 151 and HU 371, for example). Mlr1954a
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.51 +/- 1.89, 3.75, and 1.82 Msun, respectively. Mlk2012
