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.


Venus Climate Orbiter I-kernels Provided in This Data Set
=========================================================

   This data set contains the following the Venus Climate Orbiter
   (VCO, also known as PLANET-C and AKATSUKI) IK files (only the
   leading portion of the file name is shown; the extension of all
   file names is ``.ti''):

      vco_ir1_vVV   IK file containing FOV and reference frame
                    definitions for the VCO 1-um camera (IR1)
                    instrument, created by the PLANET-C IR1 Team.
 
      vco_ir2_vVV   IK file containing FOV and reference frame
                    definitions for the VCO 2-um camera (IR2)
                    instrument, created by the PLANET-C IR2 Team.
 
      vco_lac_vVV   IK file containing FOV and reference frame
                    definitions for the VCO Lightning and Airglow
                    Camera (LAC) instrument, created by the
                    PLANET-C LAC Team.
 
      vco_lir_vVV   IK file containing FOV and reference frame
                    definitions for the VCO Longwave Infrared
                    Camera (LIR) instrument, created by the
                    PLANET-C LIR Team.
 
      vco_uvi_vVV   IK file containing FOV and reference frame
                    definitions for the VCO Ultra Violet Imager
                    (UVI) instrument, created by the PLANET-C UVI
                    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.

   If this data set contains multiple IK files for a particular instrument,
   the one with the latest version (VV) supersedes all previous versions.

   In most cases these IK files

      vco_ir1_vVV.ti
      vco_ir2_vVV.ti
      vco_lac_vVV.ti
      vco_lir_vVV.ti
      vco_uvi_vVV.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.
