V/139/sdss9 The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)
Data Release 9 (469,053,874 primary sources plus 324,960,076 secondary sources); 2,674,200 spectroscopic targets. Data Release 9 is the first release of the spectra from the SDSS-III's Baryon Oscillation Spectroscopic Survey (BOSS). The photometric part contains the same sources as the Data Release 8, with a corrected astrometry. (794013950 rows)
