Fourth Catalog of Interferometric Measurements of Binary Stars: References


Note: Uniform reference codes and now a common reference file have been adopted for all USNO double star catalogs, including the latest orbit, rectilinear motions, and photometric magnitude difference catalogs, as well as the Washington Double Star Catalogue and the Fourth Interferometric Catalog. Reference codes are based on WDS Discoverer Designations and the date of publication.
