The Photometric Magnitude Difference Catalog
Listed in IVOA Registry (Virtual Observatory)
The Photometric Magnitude Difference Catalog is a collection of all double star photometric data which does not contain astrometric information and is therefore inappropriate for the Washington Double Star Catalog.
Description
Magnitude difference information can be useful in estimating mass ratios, determining photocentric positions which are color dependent, or into investigations of variability in close binary systems. Due to uncertainties in bandpass characteristics or variability, no summary line is presented, rather a complete listing of all data.
Introduction: The Photometric Magnitude Difference Catalog (hereafter Delta-M Catalog) was initiated as an internal USNO publication by C.E. Worley and remained as an internal publication for over 20 years. While private copies circulated, this is the first open presentation of these accumulated data. No ``WDS-like'' summary line is provided, rather, a complete listing of all photometric data is given.

When available, bandpass characteristics and errors are provided, as are other notes (for example, systems not in the WDS are indicated). A more detailed introduction is provided in the "dm.txt" file.
