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

   In the SPICE system, I-kernels describe how an instrument is mounted
   to the instrument platform. I-kernels also contain instrument
   field-of-view specifications, principal axes specifications and
   possibly other instrument-specific information useful in the SPICE
   context.

   The I-Kernel mounting alignment, along with knowledge of the
   spacecraft position (SP kernel) and instrument pointing (C kernel),
   allows the user to use a collection of subroutines that are part of
   the SPICELIB library, the major component of the SPICE Toolkit. These
   subroutines can be integrated into user application programs.
   Information about obtaining the SPICE Toolkit is located in the
   ``software'' subdirectory of the main directory of this dataset.

   Refer to the Kernel Required Reading (kernel.req) document provided
   with the Toolkit or available from the NAIF Node of the PDS, to get
   more information on how to access I-Kernel data.


Hayabusa I-kernels Provided in This Data Set
============================================

   This data set contains the following Hayabusa IK files (only the
   leading portion of the file name is shown; the extension of all file
   names is ``.ti''):

      amica31    IK file containing FOV and reference frame definitions
                 for the Hayabusa Asteroid Multi-band Imaging CAmera
                 (AMICA) instrument, created by the Hayabusa Joint
                 Science Team.
 
      lidar10    IK file containing FOV and reference frame definitions
                 for the Hayabusa LIght Detection And Ranging (LIDAR)
                 instrument, created by the Hayabusa Joint Science
                 Team. The LIDAR FOV defined in this file is 0.1 by 
                 0.1 degrees.
 
      lidar_v1   IK file containing FOV and reference frame definitions
                 for the Hayabusa LIght Detection And Ranging (LIDAR)
                 instrument, created by the Hayabusa Joint Science
                 Team. The LIDAR FOV defined in this file is 0.0566 by 
                 0.0566 degrees.
 
      nirs10     IK file containing FOV and reference frame definitions
                 for the Hayabusa Near InfraRed Spectrometer (NIRS)
                 instrument, created by the Hayabusa Joint Science
                 Team.
 
      xrs10      IK file containing FOV and reference frame definitions
                 for the Hayabusa X-Ray Spectrometer (XRS) instrument,
                 created by the Hayabusa Joint Science Team.

   All IK files provided in this data set are in UNIX text format,
   with a line feed character (ASCII 10) at the end of the line.

   In most cases these IK files

      amica31.ti
      lidar_v1.ti
      nirs10.ti
      xrs10.ti

   should be loaded into a user's application to process data for
   the surveying and collection phase of the mission.
