Abstract

An ongoing photometric survey of 16,000 galaxies on ESO red and blue plates is described. The galaxies of the ESO/Uppsala Catalog (Lauberts, 1982) are being PDS scanned, and the results are combined with existing photometry and supplementary observational data obtained at the 1-m ESO telescope to form a catalog for paper, magnetic-tape, and possibly video-disk publication. Details of the plate digitization, photometric calibration, and automatic parameter extraction are discussed, and a flow chart of the extraction operation and graphs of sample data are provided.
