Frame (FK) kernel file for JUICE Spacecraft Solar Array Default Frames
===============================================================================

   This frames kernel overwrites the JUICE Solar Array Frames (JUICE_SA+Y_PLAN
   and JUICE_SA-Y_PLAN) definitions from [3] and maps it to the
   JUICE Spacecraft Solar Array Default Frames frame (JUICE_SA+Y_DEFAULT and
   JUICE_SA-Y_DEFAULT) defined in [4].
   
   This allows the user to use the existing alignments and instrument frame
   definitions in the JUICE frames kernel (see ref [3]) to perform instrument
   specific mission analysis and attitude dependent science opportunity
   identification. Please refer to the section ``Using this frame'' for further
   details.
   
   NOTE THAT BY USING THIS KERNEL, THE JUICE_SA+Y_PLAN AND JUICE_SA-Y_PLAN
   FRAMES WILL BE MAPPED TO THE JUICE_SA+Y_DEFAULT AND JUICE_SA-Y_DEFAULT
   FRAMES, AND ANY CK PROVIDING ORIENTATION FOR THE JUICE_SPACECRAFT FRAME WILL
   NOT BE USED BY THE APPLICATION SOFTWARE, EVEN IF IT IS LOADED IN THE KERNEL
   POOL.

Implementation Notes
-------------------------------------------------------------------------------

   This file is used by the SPICE system as follows: programs that make
   use of this frame kernel must "load" the kernel normally during 
   program initialization. Loading the kernel associates the data items 
   with their names in a data structure called the "kernel pool". The 
   routine that loads a kernel into the pool is shown below:
                                                                               
      FORTRAN: (SPICELIB)

         CALL FURNSH ( frame_kernel_name )

      C: (CSPICE)

         furnsh_c ( frame_kernel_name );

      IDL: (ICY)

         cspice_furnsh, frame_kernel_name
         
      MATLAB: (MICE)
      
         cspice_furnsh ( 'frame_kernel_name' )

   This file was created and may be updated with a text editor or word
   processor.
   

Using this frame
-------------------------------------------------------------------------------

   This frames have been implemented to overwrite the JUICE_SA+Y_PLAN and
   JUICE_SA-Y_PLAN frame definitions provided in the JUICE Frames Definitions
   kernel ([3]) and map it to the JUICE_SA+Y_DEFAULT and JUICE_SA-Y_DEFAULT
   frames defined in the JUICE Science Operations Frames Definitions
   kernel ([4]).
   
   In order to make use of this frames kernel, this file MUST BE LOADED
   AFTER the JUICE frames definition kernel and the JUICE Science Operations
   Frames Definition kernel.
   
   A metakernel defined to use this file should look like this:
      
         ...
         
              $DATA/fk/juice_v00.tf
              $DATA/fk/juice_ops_v00.tf
              $DATA/fk/juice_sa_default_v00.tf
         
         ...
         
   (*) the example presents version 0.0 of the JUICE frames and
       JUICE Science Operations frames kernels. Newer versions of
       these files will produce the same results. 
   
   NOTE THAT BY USING THIS KERNEL, THE JUICE_SA+Y_PLAN AND JUICE_SA-Y_PLAN
   FRAMES WILL BE MAPPED TO THE JUICE_SA+Y_DEFAULT AND JUICE_SA-Y_DEFAULT
   FRAMES, AND ANY CK PROVIDING ORIENTATION FOR THE JUICE_SA+Y_PLAN AND
   JUICE_SA-Y_PLAN FRAMES  WILL NOT BE USED BY THE APPLICATION SOFTWARE,
   EVEN IF IT IS LOADED IN THE KERNEL POOL.
