The area covered by the catalog is about 4188 deg^2^. The quasar redshifts range from 0.08 to 5.41, with a median value of 1.47; the high-redshift sample includes 520 quasars at redshifts greater than four, of which 17 are at redshifts greater than five. For each object the catalog presents positions accurate to better than 0.2" rms per coordinate, five-band (ugriz) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains radio, near-infrared, and X-ray emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3800-9200{AA} at a spectral resolution of about 2000; the spectra can be retrieved from the public database using the information provided in the catalog. A total of 44,221 objects in the catalog were discovered by the SDSS; 28,400 of the SDSS discoveries are reported here for the first time. 2005AJ....130..367S https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/243 Catalog Research IsServedBy TAP VizieR generic service IsPreviousVersionOf 7252 IsServedBy Conesearch service related-to http://www.sdss.org/ : The SDSS Home Page J/AJ/123/567 : SDSS quasar catalog.
