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 is located in the SOFTWARE
   subdirectory of the main directory of this dataset. Refer to the
   KERNEL.REQ document provided with the toolkit to get more information
   on how to access I-kernel data.


Mars Pathfinder I-kernels provided in this dataset
==================================================

   This dataset contains I-kernel files for two primary MPF Lander
   instruments, IMP and ASI/MET.
   
   The IMP IK file was created before launch and went though a few
   updates during and after the mission.
   
   The ASI/MET IK file was created after the mission from the data
   provided by ASI/MET experiment team.



I-kernel file naming schema
===========================

   Each I-kernel file in this dataset is a SPICE text kernel format
   file that conforms to the UNIX text end-of-line convention.

   The name of the IMP IK file is MPF_IMP.TI. The name of the ASI/MET
   IK file is MPF_MET.TI. Corresponding label file names are MPF_IMP.LBL
   and MPF_MET.LBL.
