                         EXTRAS Directory Contents

The extras directory contains additional items which may be of use to the 
user, but which may not explicitly conform to PDS format.

For a brief tutorial on Cassini image calibration, see the 
theoretical_basis.pdf document, as well as section 5 of the CISSCAL manual,
both of which can be found in the document subdirectory on the Calbration 
archive volume.

cisscal.tar.gz - A g-zipped TAR archive containing the entire contents of
                  the cisscal directory described below. This was included
                  to avoid any filename case issues that may arise when 
                  reading the DVD filesystem on various platforms.

cisscal/ -  This directory contains the Cassini ISS Calibration (CISSCAL)
             software package, version 3.6. These files are provided as a
             service to the user, and are not guaranteed to work on all 
             system architectures or be completely free of bugs or errors.
             Note that the CISSCAL user manual can be found in the DOCUMENT
             directory of this calibration volume.
