资源简介：
The Sloan Digital Sky Survey has released its fifth Data Release (DR5). The spatial coverage of DR5 is about 20% larger than that of DR4. The photometric data in DR5 are based on five-band imaging observations of 8000 square degrees of sky, and include measures of 215 million unique objects.
Based on these photometric data, objects were selected for spectroscopy over a footprint area of 5740 square degrees. DR5 includes derived spectroscopic parameters for 1,048,960 spectra, classified into 674,749 galaxies, 154,925 stars and 90,611 quasars.
