Brief Summary
-----------------------------------------------------------------------------

   This directory contains generic and mission-specific SPICE Planetary
   Constants Kernel files for the JUICE mission. The data in these kernels
   correspond to the best knowledge of the orientation, size and shape
   of each of the JUICE targets and is released upon authorization by the
   JUICE Science Team.


File naming conventions
-----------------------------------------------------------------------------

   Naming Scheme for Generic PCKs

      The naming scheme for generic PCKs is:

         pckNNNNN.tpc

      where

         NNNNN    version number (required)(e.g. 00010);

                  If multiple versions of a generic PCK Kernel file are
                  provided, always use the latest version (unless an
                  earlier version is needed for some special reasons.)


   Naming Scheme for JUICE mission-specific PCKs

      The naming scheme for JUICE mission-specific PCKs is:

         juice_jupNNN.tpc

      where

         NNN      version number (required) (e.g. 000);

                  If multiple versions of a JUICE mission-specific PCK
                  Kernel file are provided, always use the latest version
                  (unless an earlier version is needed for some special
                  reasons.)
