Description:
    The Washington Visual Double Star Catalog, 1984.0 (WDS) is the
    successor to the Index Catalogue of Visual Double Stars, 1961.0
    (Jeffers et al., 1963), which is usually denoted as the IDS.
    The WDS is intended to contain all known visual double stars for which
    at least one differential measure has been published through the end
    of 1983. The reader is reminded that the WDS is therefore not
    inclusive of all pairs which have been more casually noted, although
    it does, in fact, include some of them. Approximately 384000
    individual means, representing over a million individual observations,
    form the basic material from which the WDS is constructed. Not
    included are a small amount of data because of unresolved questions
    concerning it. The WDS contains 73610 double stars, counting, as did
    the IDS, multiple components in the same system as separate pairs.
