Speckle Interferometry at the U.S. Naval Observatory. XIV.
Abstract
The results of 2033 intensified CCD observations of double stars, made with the 26 inch refractor of the U.S. Naval Observatory, are presented. Each observation of a system represents a combination of over 2000 short-exposure images. These observations are averaged into 1297 mean relative positions and range in separation from 0farcs54 to 58farcs96, with a mean separation of 14farcs99. This is the 14th in this series of papers and covers the period 2007 January 17 through 2007 December 31. The first two resolutions of closer companions to previously known wider pairs are also presented.
