Frame (FK) kernel file for TGO Spacecraft Mars-Nadir Power Optimized 
===============================================================================

   This frames kernel overwrites the TGO spacecraft frame (TGO_SPACECRAFT)
   definition from [3] and maps it to the TGO Mars Nadir power optimized
   frame (TGO_MARS_NPO) defined in [4].
   
   This allows the user to use the existing alignments and Instrument frame
   definitions in the TGO 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 TGO_SPACECRAFT FRAME WILL BE 
   MAPPED TO THE TGO_MARS_NPO FRAME, AND ANY CK PROVIDING ORIENTATION FOR
   THE TGO_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 TGO_SPACECRAFT
   frame definition provided in the ExoMars-2016 Frames Definitions kernel
   ([3]) and map it to the TGO_MARS_NPO frame defined in the TGO
   Science Operations Frames Definitions kernel ([4]).
   
   In order to make use of this frames kernel, this file MUST BE LOADED
   AFTER the ExoMars-2016 frames definition kernel and the TGO Science
   Operations Frames Definition kernel.
   
   A metakernel defined to use this file should look like this:
      
         ...
         
              $DATA/fk/em16_tgo_v00.tf
              $DATA/fk/em16_tgo_ops_v00.tf
              $DATA/fk/em16_tgo_sc_mars_noa_v01.tf
         
         ...
         
   (*) the example presents version 0.0 of the ExoMars-2016 frames and
       TGO Science Operations frames kernels, and it is intended just
       for illustration purposes. 
   
   NOTE THAT BY USING THIS KERNEL, THE TGO_SPACECRAFT FRAME WILL BE 
   MAPPED TO THE TGO_MARS_NPO FRAME, AND ANY CK PROVIDING ORIENTATION FOR
   THE TGO_SPACECRAFT FRAME WILL NOT BE USED BY THE APPLICATION SOFTWARE,
   EVEN IF IT IS LOADED IN THE KERNEL POOL.
