Beginning of ReadMe : I/246 The ACT Reference Catalog (Urban+ 1997) ================================================================================ The ACT Reference Catalog Urban S.E., Corbin T.E., Wycoff G.L. <U.S. Naval Observatory, Washington D.C. (1997)> ================================================================================ ADC_Keywords: Positional data; Proper motions ; Astrographic zones; Historical catalog; Photographic catalog; Surveys; Cross identifications Abstract: The U.S. Naval Observatory has completed the compilation of the ACT Reference Catalog, containing 988,758 stars covering the entire sky. The motivation behind the ACT was to provide accurate proper motions for the majority of the stars in the Tycho Catalogue (ESA SP-1200). To do this, positions from new reductions of the Astrographic Catalogue (AC 2000) were combined with those of Tycho. The large epoch span between the two catalogs yields proper motions about an order of magnitude more accurate than those published in the Tycho Catalogue. The astrometric data contained in the ACT Reference Catalog include positions, proper motions and error estimates. These are on the Hipparcos System (J2000.0) for epoch J2000.0. Photometric data (B and V) from Tycho are included. Additionally, cross references to the Tycho, AC 2000, Bonner Durchmusterung (BD), Cordoba Durchmusterung (CD), Cape Durchmusterung (CPD), Henry Draper (HD) and Hipparcos Catalogues are given.
