... After matching image point sources to ob jects in each of the catalogs and fitting world coordinate systems to them using the IMWCS program, we find mean residuals between observed and catalog star positions of between 0. 09 and 0. 25 for the latest catalogs. ... Unix shell scripts written for each catalog set up an initial FITS header for each of the 1728 images with the center being the mean position of the ob jects found in that image. ... Catalog Fits of Various Catalogs to 1728 Images. ...
