Part of the Institute for Astronomy at the University of Edinburgh, the Wide-Field Astronomy Unit maintains the SuperCosmos Sky Surveys Web site. The SuperCosmos is an advanced photographic plate-digitizing machine that produces data derived from the scans of photographic Schmidt survey plates. Visitors can "extract images (pixel data) up to 15 arcmin across and/or object catalogues covering up to 100 sq. degrees. The data cover three wavebands (BRI), with one colour (R) represented at two epochs." March of 2002 has brought a new release of data that bring the database even closer to completion.
