SPECIAL VERSION OF CCDRED PACKAGE FOR MULTI-AMPLIFIER CCD IMAGES

The package has a special quad version of CCDPROC that processes
multi-amplifier CCD images in a particular format.  See help topic
"quadformat" for a description of the format.  The task QUADPROC is
largely obsoleted by the quad version of CCDPROC but may be used by
those familiar with the ARED.QUAD package or to use features in the
standard CCDPROC that are not in the quad version.  Those features
include line-by-line overscan functions.

		ALTERNATIVE TASKS

       quadproc - Process multi-amplifier CCD images (see also ccdproc)
   qdarkcombine - Combine and process dark count images using quadproc
