Table for field ranges

The images from the SDSS project are organized into stripes. These are long images, 24,000 pixels wide (2.5 degrees), and typically over 1 million pixels long (120 degrees). The SDSS covers the northern sky with 45 overlapping stripes. The stripes are designed to avoid the dust in the plane of the Milky Way, shown as the red areas in the diagram at right.
Each stripe is merged from two runs, taken on separate nights. The telescope can complete only a single 8-hour run in any given night. Each run consists of 6 camcols (camera columns); each camcol corresponds to each array of CCD detectors of our camera. Each camcol takes images in five colors.
