II/306/sdss8 The SDSS Photometric Catalog, Release 8 (Adelman-McCarthy+, 2011)
Data Release 8 (469,053,874 primary sources, plus 324,960,076 secondary sources). Notice that the new reductions used for the SDSS-DR8 introduced some errors in the astrometry, especially at declinations δ≥41°; when possible, the astrometry of the SDSS-DR7 (Cat. II/294) should be preferred. (324960076 rows)
