BepiColombo Auxiliary Instrument Kernel
===============================================================================

   This Instrument Kernel (IK) file contains Field-Of-View (FOV) definitions
   for a few BepiColombo instruments and structures that don't yet or will
   never have their own IKs.

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.

   * SPICEPY is a non-official, community developed Python wrapper for the
     NAIF SPICE toolkit. Its development is managed on Github.

Naming Conventions
---------------------------------------------------------------

   All names referencing values in this I-kernel start with the characters
   'INS' followed by the NAIF BepiColombo spacecraft ID number (MPO: -121;
   MM0: -68) and then followed by a NAIF three digit codes for the given
   instrument.

   The remainder of the name is an underscore character followed by the
   unique name of the data item.  For example, the HGA boresight
   direction in the MPO_SPACECRAFT frame (see [2]) is specified by:

      INS-121038_BORESIGHT

   The upper bound on the length of the name of any data item identifier
   is 32 characters.

   If the same item is included in more than one file, or if the same item
   appears more than once within a single file, the latest value supersedes
   any earlier values.


Mounting Alignment
--------------------------------------------------------

   Refer to the latest version of the MPO Frames Definition Kernel
   (FK) [3] for the MPO structures reference frame definitions and
   mounting alignment information.


Antenna FOVs
----------------------------------------------------------

   This section defines FOVs for the following instruments or structures:

          NAME                   ID     HALFSIZE   SHAPE   BSIGHT
      -----------------------  -------  --------  -------  ------
          MPO_HGA              -121023   2.5 deg   cone      +Z


   The FOVs are defined in this data block.

      \begindata

         INS-121023_FOV_CLASS_SPEC       = 'ANGLES'
         INS-121023_FOV_SHAPE            = 'CIRCLE'
         INS-121023_FOV_FRAME            = 'MPO_HGA'
         INS-121023_BORESIGHT            = ( 0.0, 0.0, 1.0 )
         INS-121023_FOV_REF_VECTOR       = ( 1.0, 0.0, 0.0 )
