discov_num notes refcode
HU 575 Identification of the ascending node, based on a few Mt. Wilson
spectra, is uncertain at this small difference in magnitude. Mlr1952b
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 0.99 +/- 0.19, 1.28, and 0.55 Msun, respectively. Mlk2012
