Deep Impact/EPOXI I-kernels Provided in This Directory
======================================================

   This directory contains the following Deep Impact Flyby (DIF)/EPOXI
   and Deep Impact Impactor (DII) IK files (only the leading portion of
   the file name is shown; the extension of all file names is ".ti"):

      dif_hri_vVV   IK files for the DIF High Resolution Imager (HRI)
                    instrument

      dif_mri_vVV   IK files for the DIF Medium Resolution Imager (MRI)
                    instrument

      dii_its_vVV   IK files for the DII Impactor Targeting Sensor (ITS)
                    instrument

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


Deep Impact/EPOXI IK File Naming Scheme
========================================

   The Deep Impact/EPOXI IKs provided in this directory are named
   according to the following scheme:

      sc_inst_vXX.ti

   where:

      sc        is the name of the spacecraft: "dif" or "dii";

      inst      is the name of the instrument: "hri" for High
                Resolution Imager, "mri" for Medium Resolution Imager,
                "its" for Impactor Targeting Sensor;

      vXX       is the file version number;

   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.)
