| 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.) |
