SMART-1 FK Files
=============================================================================

  Last Update: 12 MAY 2006

  This "aareadme.txt" file describes the contents of the KERNELS/FK directory
  of the SMART-1 SPICE data server. It also provides the file naming
  conventions used for the SMART-1 FK kernels, and it provides identification
  of the most current version of each kind of FK file.

  All these FK files are produced manually  with the information supplied by
  SMART-1 teams describing the frames for the spacecraft and its science
  instruments. Some of these FK files (for tracking stations) are provided
  specifically for the Radio Science investigation.

  All FK files (*.TF) 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 2a]

  Contact Jorge Diaz del Rio (jdiaz@rssd.esa.int) or Joe Zender 
  (Joe.Zender@esa.int) if you have any questions.

SMART-1 FK Directory Structure
=============================================================================
  aareadme.txt       Text file describing the directory structure, the naming
                     conventions for the FK, and the current version(s) of
                     each FK type.

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

  Name                   Comments

  EARTHFIXEDIAU.TF       This kernel makes the IAU_EARTH frame coincide with 
                         the earth fixed reference frame. 

  EARTHFIXEDITRF93.TF    This kernel makes the ITRF93 frame coincide with the
                         earth fixed reference frame.

  EARTH_TOPO_yymmdd.TF   FK kernel for the topocentric reference frames for
                         the Deep Space Network (DSN) stations. This kernel was
                         released on yy-mm-dd.

  RSSD0001.TF            FK kernel defining a number of mission independent
                         frames that could be used by any of the users of any
                         of the ESA planetary missions and that are not 
                         ``built'' in the SPICE toolkit. The following frames
                         related to the Moon are implemented: Moon Mean
                         Equator of Date (LME), Moon-centric Solar Ecliptic
                         of Date (LSE) and Moon Mean Equator of date J2000
                         (LME2000).

  SMART1_Vxx.TF          FK containing the complete set of frame definitions 
                         for the SMART-1 spacecraft including definitions for
                         the SMART-1 fixed platforms and SMART-1 science
                         and technology demonstration instrument frames.
                         This kernel also contains NAIF ID/name mapping for
                         the SMART-1 instruments.
