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.)
