General information about SPICE I-kernels
=========================================

   In the SPICE system, I-kernels describe how an instrument is mounted
   to the instrument platform. I-kernels may also contain instrument
   field-of-view specifications, principal axes specifications, etc.
 
   The I-kernel mounting alignment, platform orientation, along with
   knowledge of the spacecraft position (SP kernel) and instrument
   pointing (C kernel), allows the user to use SPICELIB to calculate
   the pointing of instruments. The data contained in I-kernel files
   can be accessed and manipulated by a collection of FORTRAN 77
   subroutines which are part of the SPICELIB library. It is used in
   conjunction with other data. The SPICELIB subroutines can be
   integrated into user application programs. The SPICE system toolkit
   for a number of computer platforms or information regarding how it
   can be obtained is located in the SOFTWARE sub-directory of the main
   directory of this data set.
 
   Refer to the KERNEL.REQ document provided with the toolkit or
   available from the NAIF Node of PDS if SPICE toolkit is not included
   with this data set to get more information on how to access I-kernel
   data.
