Chm2004 (Photometry, coordinates, and astrometry from rNLTT. Astrometry from early
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.)
