(Photometry, coordinates, and astrometry from rNLTT. Astrometry from early |
|
| Chm2004 |
|
versions of 2MASS and UCAC, with date given only as "circa 2000". Measures |

|
identical to discovery observations - predominantly close pairs - were assumed |
|
| Chm2004 |

not new observations, so not included in WDS. Similar concerns when primary and |

|
secondary magnitudes or proper motions were the same.) |
