cds-question@unistra.frmultiple-starsinterferometryThe results of 4747 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 2667 mean relative positions and range in separation from 0.328" to 95.9", with a median separation of 8.673". Eight orbits are improved. This is the 22nd in this series of papers and covers the period 2016 January 4 through 2016 December 29.2017AJ....154..183Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/183CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)B/denis : The DENIS database (DENIS Consortium, 2005)II/311 : WISE All-Sky Data Release (Cutri+ 2012)J/AJ/117/1905 : Speckle interferometry at USNO.
