Explanation of the anomalous magnitude WDS list.
The data in this list are entries in the United States Naval Observatory's
WDS catalog whose visual magnitude listings are not matched by other catalogs.
Each entry in the WDS catalog was read. A given pair was rejected if the
data in the notes column had an:
- I: The pair's identification is uncertain.
- K: K band infrared magnitude.
- R: Johnson red band magnitude.
- X: The pair is dubious.
Please further note that WDS entires without a precise position or if
the primary is fainter than 17mv or brigher than 6mv are not included in this
study as well.
Column explanation:
- WDS Id The WDS identifier for the binary.
- Discoverer The binary Discover's identifier for the binary.
- J2000 The binary's coordinates, from the WDS precision coordnates.
- mva-mvb The WDS visual magnitudes of the primary and secondary.
- Rho The most recent separation of the pair in arc seconds.
- Note: Separations greater than 10" are shown in
Bold type.
- Theta The most recent position angle of the pair in degrees.
- Dmv The difference between the WDS primary star mv and the closest
catalog mv.
- Comment
- C: A WDS pair with magnitudes with a single digit mv listing (e.g. 9.4). These
are shown in white.
- P: A WDS pair with magnitudes with a double digit mv listing (e.g. 9.47). These
are shown in green.
- N: A WDS pair with notes supplied by the USNO. These are shown in yellow.
- S: A WDS pair with magnitudes that are greater than 4mv from the
closest catalog mv. These are shown in magenta.
- X: A WDS pair with no catalog listing within 10" of it.
These are shown in red.
Note: If you click on a comment that is not an "X", a new page will be
created that will show the catalog stars within 10" of the WDS pair.
