#_Title S04_kernels.def - List of Cassini NAIF SPICE kernels
#
#_Desc S04_kernels.def contains a list of all the NAIF SPICE kernels
#      relevant to the Cassini cameras. This file is referred to
#      in all ISIS Cassini applications that require such 
#      information. It should contain a list of all files required to
#      determine spacecraft telemetry, orientation, timing, and all
#      details relating to the operation of the cameras and platform
#      at any time during the mission. 
#
#      In order to get proper spacecraft navigation and instrument
#      orientation there are certain files that must be referenced.
#      We use SPICE kernels provided by NAIF.  They provided a robust
#      software system library that accesses these data to get all
#      necessary ephemeris data for an instrument at given time.  The
#      SPICE software library loads the appropriate files and then is
#      able to provide "snapshots" of spacecraft location and instrument
#      platform orientation to resolve pointing geometry.
#
#      The NAIF software system requires at least (and, sometimes,
#      at most) 1 type of the following files:
#
#        Leap Seconds file       - .tls file
#        Planetary Constants     - .tpc file
#        Spacecraft Clock Count  - .tsc file
#        Instrument Mount Kernel - .ti  fle
#        Planetary Ephemerides   - .bsp fle
#
#      These files are located under the "Standard Kernels" section.
#      There should be no more that one of these types of file loaded
#      from this section (i.e., no files with the same file extension).
#
#      What remains is to load the dowlinked telemetry from the mission
#      spacecraft.  These will be a series of SPK or SPacecraft Kernels
#      and CK, Camera Kernels.  This file is created for the Cassini 
#      mission and the ISS instruments on that spacecraft.  It has 
#      specific SPK and CK file that are designed to parallel one another
#      in time/phase of the mission.  There, generally, can be any number 
#      of these files as long as the system maximum is not exceeded.
#
#      Note that the order SPICE kernels are loaded into the NAIF software
#      system is important.  Typically, the last file loaded of a given 
#      type takes precedence of previous files loaded of the same type.
#      The software will not attempt to load any files that do not exist
#      so you can list all the anticipated kernels in this file without
#      having to change it.  To add a new kernel, simply make a copy of
#      of this file and append newer time coverage files to the end of
#      appropriate section or end of the file.  Filenames may contain
#      environment variables or full pathes to them.  ISIS uses environment
#      variables to allow for distribution with the software.
