discov_num notes refcode
COU1688 AB: A premature orbit has been calculated with very sparse data, since
most of the observations are negative.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 3.58 +/- 1.35, 2.16, and 0.95 Msun, respectively. Mlk2012
LDS9155 AC: Old LDS6155. HIP 16467. See Allen et al. (2000) for information on AlC2000
metallicity, age, galactic orbital parameters, etc.
