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 NAIF 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.


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

   All files are in IEEE text format and must be copied using ftp ASCII
   transfer to any non-UNIX workstation. 

   The Cassini IK file naming schema is as follows (Only the leading
   portions of the file names are shown; the file name extensions of
   the I-kernel are always ".ti"):

        [cas]_[IIIII]_v[VV]

     where:

           [cas]     Constant prefix indicating Cassini IK file;
 
           [IIIII]   Instrument or subsystem acronym;
 
           [VV]      File Version.

     If multiple versions of an IK file are provided for an instrument,
     always use the latest version (unless an earlier version is needed
     for some special reasons.)


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.
