Beginning of ReadMe : V/39 4th Catalog of Orbits of Visual Binaries (Worley+, 1983) ================================================================================ The Fourth Catalog of Orbits of Visual Binary Stars Worley C.E., Heintz W.D. <Publ. U.S. Naval Obs. (2) 24, part VII (1983)> =1983PUSNO..24g...1W (SIMBAD/NED RefCode) ================================================================================ ADC_Keywords: Binaries, orbits ; Stars, double and multiple Description: The Finsen-Worley Catalog (1970), supplemented by all subsequently published orbits known to Worley and Heintz as of 1 July 1982 formed the basis for the present compilation. Practically all stars having visual orbits were reobserved in the preceding decade, often repeatedly either with micrometers or with speckle interferometers. Astrometric solutions are included but only if they were judged to be relatively certain. Orbits with period greater than 4000 years and hyperbolic orbits were rejected as being unreliable. The catalog contains 928 orbits of 847 systems (counting triples as two systems). There are 23 orbits of unresolved systems. The catalog contains for each system the names of the star and the components involved, the 1900 position, the ADS number, the magnitude and spectral type for each component, the orbital elements, the equinox of the node, the quality of the orbit, the date of the last observation, the inclusive dates for which an ephemeris is given by the author, the computer of the orbit, and a reference.
