A 1634 nu 2 Boo = 53 Boo. An example of adequate resolution provided only by
speckle.
1921.400: This observation is highly uncertain. Mrr1922
Omega for Baize (1985) solution corrected from 47.5 to 227.5 Baz1985b
degrees. Ruy1995
1985.2002, 1985.2494: These two measurements are not precise because
this interferometric binary is only marginally resolved with a 2-m
telescope. Estimates of rho and theta are deduced from the elongation
of the central peak in the autocorrelation. Bnu1986
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 4.82 +/- 1.34, 6.07, and 1.82 Msun, respectively. Mlk2012
