Speckle Interferometry at the U.S. Naval Observatory. XXII

Abstract

The results of 4,747 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 two thousand short-exposure images. These observations are averaged into 2,667 mean relative positions and range in separation from 0.328" to 95.9", with a median separation of 8.673". Four orbits are improved. This is the 22nd in this series of papers and covers the period 4 January 2016 through 29 December 2016.
