discov_num notes refcode
STF1604 AB: Mt. Wilson spectral types are G2 and K8. A is a spectroscopic
binary, and slightly variable. Large relative proper motion, coupled
with the fact that the C component is brighter than B, has led to some
confusion in identification of components.
AB: NLTT 29769/29772 Chm2004
HIP 59272. Tok2011a
BC: Rectilinear solution by Friedman et al. (2012). USN2012a

Chm2004 versions of 2MASS and UCAC, with date given only as "circa 2000". Measures
Chm2004 identical to discovery observations - predominantly close pairs - were assumed
Chm2004 not new observations, so not included in WDS. Similar concerns when primary and
Chm2004 secondary magnitudes or proper motions were the same.)
