Date 20 Aug 2004
Subject astro-ph
AbstractA list of 705 new Northern Celestial Hemisphere common proper motion pairs as derived from the Second U.S. Naval Observatory CCD Astrograph Catalog is presented, along with details of their separation, motion, brightness and colour. Objects of particular interest are noted, and the use of the catalogue for such work gauged.

Review title: Flawed analysis of incorrect data
Reviewer: reviewer637
Date: 04 April 2007 at 08:46 GMT.

The basic idea behind the article, that is using common proper data to identify possible binary stars, is sound.

Unfortunately the methods used to identify potential candidates are fatally flawed relying as they do on the ratios of the proper motions of the two components rather than on the difference between the two values.

It is believed that the author now accepts that at least 1/3rd of the pairs listed are totally spurious.
