MEX IK Files
=============================================================================

  Last Update: 11 MAY 2006

  This "aareadme.txt" file describes the contents of the KERNELS/IK directory
  of the MEX SPICE data server. It also provides the file naming conventions
  used for the MEX IK kernels, and it provides identification of the most
  current version of each kind of IK file.

  All these IK files are produced manually with the information supplied by
  Mars Express teams describing the science instruments.

  All IK files (*.TI) contained in this directory are unix text
  files. These may be used in a non-compatible text environment by using the
  ASCII mode of FTP to port the files. [Ref 1a]

  Contact Jose Luis Vazquez (jlvazquez@sciops.esa.int) or Joe Zender 
  (Joe.Zender@esa.int) if you have any questions.

  aareadme.txt       Text file describing the directory structure, the naming
                     conventions for the IK, and the current version(s) of
                     each IK type.

  former_versions    Subdirectory that contains obsolete versions of the IK
                     files that have been updated in the Current IK Kernel
                     Set.
