A 604 Aitken (1937) put together into a single mean his measures in the A__1937b
years 1931 and 1934, but these should be considered separately, as a
reversal of quadrant may have taken place between. Period is probably
of order 50y. Mlr1954a
Toledo's elements, residuals, and ephemeris are mutually
inconsistent. The quoted elements have been reconstructed by Finsen
to fit the published residuals. Zae1963
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 3.13 +/- 2.53, 3.07, and 1.10 Msun, respectively. Mlk2012
