The EXTRAS directory contains files which facilitate the use of the           
data on the disk, but which are not actually required for the use or          
understanding of those data.  On this particular disk, the EXTRAS
directory contains files that are used internally by the PDS, but 
that are not of any use to scientific users of the disk.
