	II/306	355297		The SDSS Photometric Catalog, Release 8 (Adelman-McCarthy+, 2011) ReadMe+ftp 2011yCat.2306....0A Similar Catalogs This catalogue is obsoleted by VizieR Post annotation
1.	II/306/sdss8		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. (Note) (324960076 rows) metaII/306/sdss8
