The Early Data Release

The Early Data Release of the Sloan Digital Sky Survey consists of five-band images and measured parameters for all detected sources, as well as spectra, redshifts and other spectroscopic parameters. While these data are derived from commissioning observing runs, the quality of the data and calibrations already support a wide range of scientific applications. The Early Data Release also includes various user interfaces to search the database.
