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 subdirectory of the main
   directory of this dataset.
   
   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.


Stardust I-kernels provided on this volume
==========================================

   The following Stardust I-Kernel files are provided on this volume
   (only name portion of the file name is shown; the extension part of
   all file names is ".ti"):
   
      sdu_navcam_vNN   Stardust Navigation Camera IK file containing
                       instrument optics, FOV geometry and other
                       parameters;
 
      sdu_dfmi_vNN     Stardust Dust Flux Monitor Instrument IK file
                       containing instrument detector mounting and
                       other parameters;

   If multiple versions of an IK file are provided for an instrument,
   the latest version supersedes all earlier versions.


Kernel file details
===================

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