General information about SPICE FRAMES kernels
==============================================

   In the SPICE system, the FRAMES kernel (FK) contains information
   required to define reference frames used in a particular mission. This
   information includes sources of orientation and origin location for
   these frames and inter-connections between these frames and other
   frames supported within the SPICE system.

   The frame definitions information contained in the FK files can be used
   by 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 Frames Required Reading (frames.req) document provided
   with the toolkit or available from the NAIF Node of the PDS, to get
   more information on how to access FK data.


Deep Impact FRAMES Kernels Contained in This Directory
======================================================

   The following Frames Kernel files are included on this volume (only
   name portion of the file name is shown on the right; the extension
   of all file names is ".tf"):
   
      di_vNN    The Deep Impact Frames kernel files containing frame
                definitions for the Deep Impact Flyby and Impactor
                spacecraft, their science instruments, and antennae.


Deep Impact FK File Naming Scheme
=================================

   The Deep Impact FKs provided on this volume are named according to
   the following scheme:

      di_vXX.tf

   where:

      vXX       is the file version number;

   If multiple versions of an FK file are provided, 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 FK file is provided in
   metadata included inside the descriptive text area of the file. This
   information can be viewed using any text editor.
