Lists or enumerations of astronomical data relevant to astronomy, navigation, geodesy, and space science applications. Astronomical catalogs vary a great deal in form and content depending upon the type of the data and the objects to which they are referring. The essential data may be positions and motions of the celestial objects, magnitudes, spectra, radial velocities of stars, or energy fluxes. The celestial objects may be stars, galaxies and other galactic and extragalactic objects, or solar system bodies, which are generally ordered by increasing right ascensions and identified by a catalog number. Catalogs are either derived directly from observations or are compiled from different sources.
