Beginning of ReadMe : I/149A Fifth Fundamental Catalogue (FK5) Part I (Fricke+, 1988) ================================================================================ Fifth Fundamental Catalogue (FK5) Part I Fricke W., Schwan H., Lederle T. (in collaboration with Bastian U., Bien R., Burkhardt G., du Mont B., Hering R., Jaehrling R., Jahreiss H., Roeser S., Schwerdtfeger H.M., Walter H.G.) <Veroeff. Astron. Rechen-Institut Heidelb.

The machine version of the catalog contains the positions and proper motions of the Basic FK5 stars for the epochs and equinoxes J2000.0 and B1950.0, the mean epochs of individual observed right ascensions and declinations used to determine the final positions, the mean errors of the final positions and proper motions for the reported epochs, and ancillary data such as magnitudes, spectral types, parallaxes, radial velocities, and cross identifications to other catalog designations. Introduction: The Basic FK5 is the successor to the FK4 (Fricke & Kopff 1963) and contains the 1535 classical fundamental stars used to define the latter system. It represents a revision of the FK4 and results from the determination of systematic and individual corrections to the mean positions and proper motions of the FK4, the elimination of the error in the FK4 equinox, and the introduction of the IAU (1976) system of astronomical constants. About 300 catalogs providing star positions obtained from throughout the world are included in the FK5. This document should be used only to supplement the information contained in the source reference. The latter should be consulted for more detailed information regarding the motivation for construction of the FK5, the determination of its equator and equinox, the expressions for general precession, a discussion of the FK5 system, systematic differences between the FK4 and FK5, the transformation of observational catalogs to the FK5 system and to the reference system J2000.0, and more thorough descriptions of the data contained in the FK5 catalog.
