WISPR Instrument Kernel
===========================================================================

   This instrument kernel (I-kernel) contains references to mounting
   alignment, operating modes, and timing as well as internal and FOV
   geometry for the Solar Probe Plus WISPR instrument.


Version and Date
---------------------------------------------------------------

   The TEXT_KERNEL_ID stores version information of loaded project text
   kernels.  Each entry associated with the keyword is a string that
   consists of four parts: the kernel name, version, entry date, and type.
   For example, the frame kernel might have an entry as follows:

      \begindata
      TEXT_KERNEL_ID += 'SPP_WISPR V0.0.2 16-JUN-2016 IK'
      \begintext

   Version 0.0.2 -- June 16, 2016 -- Scott Turner
   
      Altered ID codes to fall in the standard NAIF conventional range
      [-96000, -96999] for SPP.

   Version 0.0.1 -- June 15, 2016 -- Angelos Vourlidas

      Updated field of view definitions from original square to rectangular
      fields.

   Version 0.0.0 -- April 30, 2015 -- Scott Turner

      Initial prototype version release with nominal alignments and FOV
      definitions.

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

   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.


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

   As we don't have an officially sanctioned NAIF ID code range for
   Solar Probe Plus yet, this kernel has notional ID codes.  These
   ID codes violate NAIF conventions for instruments, but are 
   consistent with the frame ID codes present in the corresponding
   orbiter frame kernel.


WISPR Inner Telescope Field of View Definition
---------------------------------------------------------------

   The WISPR inner telescope has a 40.9 x 38.4 degree rectangular field
   of view.  The boresight is the Z-axis of the SPP_WISPR_INNER frame, 
   as defined in the SPP orbiter frame kernel, with the other principal
   axes aligned with the X/Y axes of that frame.  Resulting in the 
   following field of view definition:

      \begindata
	 INS-96100_FOV_FRAME       = 'SPP_WISPR_INNER'
	 INS-96100_FOV_SHAPE       = 'RECTANGLE'
	 INS-96100_BORESIGHT       = ( 0.0, 0.0, 1.0 )
	 INS-96100_FOV_CLASS_SPEC  = 'ANGLES'
	 INS-96100_FOV_REF_VECTOR  = ( 0.0, 1.0, 0.0 )
	 INS-96100_FOV_REF_ANGLE   = ( 20.45 )
	 INS-96100_FOV_CROSS_ANGLE = ( 19.2 )
	 INS-96100_FOV_ANGLE_UNITS = ('DEGREES')
      \begintext


WISPR Outer Telescope Field of View Definition
---------------------------------------------------------------

   The WISPR outer telescope has a 59.2 x 55.4 degree rectangular field
   of view.  The boresight is the Z-axis of the SPP_WISPR_OUTER frame, 
   as defined in the SPP orbiter frame kernel, with the other principal
   axes aligned with the X/Y axes of that frame.  Resulting in the 
   following field of view definition:

      \begindata
	 INS-96120_FOV_FRAME       = 'SPP_WISPR_OUTER'
	 INS-96120_FOV_SHAPE       = 'RECTANGLE'
	 INS-96120_BORESIGHT       = ( 0.0, 0.0, 1.0 )
	 INS-96120_FOV_CLASS_SPEC  = 'ANGLES'
	 INS-96120_FOV_REF_VECTOR  = ( 0.0, 1.0, 0.0 )
	 INS-96120_FOV_REF_ANGLE   = ( 29.6 )
	 INS-96120_FOV_CROSS_ANGLE = ( 27.7 )
	 INS-96120_FOV_ANGLE_UNITS = 'DEGREES'
