Frame (FK) kernel file for MPO Spacecraft Mercury-Nadir Power Optimized 
===============================================================================

   This frames kernel overwrites the MPO spacecraft frame (MPO_SPACECRAFT)
   definition from [3] and maps it to the MPO Mercury Nadir power optimized
   frame (MPO_MERCURY_NPO) defined in [4].
   
   This allows the user to use the existing alignments and instrument frame
   definitions in the MPO 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 MPO_SPACECRAFT FRAME WILL BE 
   MAPPED TO THE MPO_MERCURY_NPO FRAME, AND ANY CK PROVIDING
   ORIENTATION FOR THE MPO_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 SPICELIB
   routine FURNSH loads a kernel into the pool as 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' )
 
     PYTHON: (SPICEYPY)*
 
       furnsh( frame_kernel_name )
 
   In order for a program or routine to extract data from the pool, the
   SPICELIB routines GDPOOL, GIPOOL, and GCPOOL are used.  See [2] for
   more details.
 
   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 MPO_SPACECRAFT
   frame definition provided in the MPO Frames Definitions kernel ([3])
   and map it to the MPO_MERCURY_NPO frame defined in the MPO
   Science Operations Frames Definitions kernel ([4]).
   
   In order to make use of this frames kernel, this file MUST BE LOADED
   AFTER the MPO frames definition kernel and the MPO Science Operations
   Frames Definition kernel.
   
   A metakernel defined to use this file should look like this:
      
         ...
         
              $DATA/fk/bc_v00.tf
              $DATA/fk/bc_ops_v00.tf
              $DATA/fk/bc_mpo_sc_mer_npo_v00.tf
         
         ...
         
   (*) the example presents version 0.0 of the MPO frames and
       MPO Science Operations frames kernels. Newer versions of
       these files will produce the same results. 
   
   NOTE THAT BY USING THIS KERNEL, THE MPO_SPACECRAFT FRAME WILL BE 
   MAPPED TO THE MPO_MERCURY_NPO FRAME, AND ANY CK PROVIDING
   ORIENTATION FOR THE MPO_SPACECRAFT FRAME WILL NOT BE USED BY THE
   APPLICATION SOFTWARE, EVEN IF IT IS LOADED IN THE KERNEL POOL.
