The Index Catalogue of Visual Double Stars, or IDS, is a catalog of double stars. It was published by Lick Observatory in 1963 and contains measurements for 64,250 objects, covering the entire sky.^{[1] [2]} The database used to construct this catalog was later transferred from Lick Observatory to the United States Naval Observatory, where it became the basis for the Washington Double Star Catalog.^[3]
