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.


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

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


      SEL_HDTV_V01   IK file containing FOV and reference frame
                     definitions for the SELENE High Definition
                     Television (HDTV), created by Y. Yamamoto.
 
      SEL_LALT_V01   IK file containing FOV and reference frame
                     definitions for the SELENE Laser Altimeter
                     (LALT) instrument, created by the LALT Team.
 
      SEL_MI_V01     IK file containing FOV and reference frame
                     definitions for the SELENE Multi-band Imager
                     (MI) instrument, created by the SELENE LISM
                     Team.
 
      SEL_SP_V01     IK file containing FOV and reference frame
                     definitions for the SELENE Spectral Profiler
                     (SP) instrument, created by the SELENE LISM
                     Team.
 
      SEL_TC_V01     IK file containing FOV and reference frame
                     definitions for the SELENE Terrain Camera
                     (TC) instrument, created by the SELENE LISM
                     Team.

      SEL_XRS_V01    IK file containing FOV and reference frame
                     definitions for the SELENE X-ray fluorescence
                     Spectrometer (XRS) instrument, created by the
                     SELENE XRS 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

      SEL_HDTV_V01.TI
      SEL_SP_V01.TI
      SEL_MI_V01.TI
      SEL_TC_V01.TI
      SEL_XRS_V01.TI

   should be loaded into a user's application to process data for
   the science phase(s) of the mission.


Kernel File Details
===================

   The most detailed description of the data in an IK file is provided
   in metadata included inside the descriptive text areas within the
   file. This information can be viewed using any text editor.
