Scientific paper

The present catalog is a subset of the data release 7 of the Sloan Digital Sky Survey (SDSS), restricted to primary and secondary photo objects (i.e. objects from PhotoPrimary of PhotoSecondary tables) and restricted to the columns described in the "Byte-by-Byte" description below. The complete SDSS data release 7 catalog is available from http://www.sdss.org/dr7/. Compared to data release 6 (Cat. II/282), this subset includes in addition the 'clean' flag.
This seventh release represents the completion of the SDSS Legacy project, which consists of an imaging survey in five bands (ugriz) over a contiguous 7646 sq.degrees high-latitude elliptical region in the Northern Galactic Cap, plus an additional 750 sq.degrees in the Southern Galactic Cap, together with spectroscopy of complete samples of galaxies and quasars covering about 8200 sq.degrees. The total imaging area in the Legacy survey is 8423 sq.degrees.
Funding for the SDSS has been provided by the Alfred P. Sloan Foundation, the Participating Institutions, the National Aeronautics and Space Administration, the National Science Foundation, the U.S. Department of Energy, the Japanese Monbukagakusho, the Max Planck Society, and the Higher Education Funding Council for England.
The SDSS is a joint project of The University of Chicago, Fermilab, the Institute for Advanced Study, the Japan Participation Group, The Johns Hopkins University, the Korean Scientist Group, Los Alamos National Laboratory, the Max-Planck-Institute for Astronomy (MPIA), the Max-Planck-Institute for Astrophysics (MPA), New Mexico State University, University of Pittsburgh, University of Portsmouth, Princeton University, the United States Naval Observatory, and the University of Washington. Apache Point Observatory, site of the SDSS telescopes, is operated by the Astrophysical Research Consortium (ARC).
