IV/915      BD-AGK3 Cross Index (Warren 1978)
================================================================================
BD-AGK3, with Non-BD Stars Omitted
    Warren Jr. W.H.
    <CDS Bull. No. 15, p. 116 (1978)>
================================================================================
ADC_Keywords: Cross identifications

Description:
   The machine-readable cross identification catalogs (Warren 1978) have been
   prepared by extracting AGK3 and BD numbers from the magnetic tape version
   of the AGK3 (Dieckvoss et al. 1975).  After preparation of the AGK3-BD
   file, which contains all stars in the AGK3, the file was sorted according
   to BD number and rearranged so that the BD number occurs at the beginning
   of each record.  During the sorting operation, all AGK3 stars having no BD
   numbers were omitted.  The catalog is especially useful for finding BD
   stars in the AGK3 catalog, since precession has moved stars across
   declination boundaries and it often has been necessary to examine more than
   one AGK3 zone to locate (or confirm the absence of) a BD star in the
   catalog.  The catalog includes BD numbers, component designations for
   multiple stars and BD supplemental stars, and AGK3 numbers.
