Prototype Mars Express SPK File (based on STAT input data)
=========================================================================
 
     Created by Boris Semenov, NAIF/JPL, November 10, 2000
 
 
Objects in the Ephemeris
--------------------------------------------------------
 
     This file contains ephemeris data for the Mars Express (MEX)
     spacecraft. Since NAIF ID code for MEX has not been assigned yet
     at the time when this file was created, bogus ID code -999 is
     used in the file.
 
 
Approximate Time Coverage
--------------------------------------------------------
 
     This file covers the following time span:
 
      Start of Interval (ET)              End of Interval (ET)

Status
--------------------------------------------------------
 
     This file was created specifically to support Tom Duxbury's
     preliminary analysis needs.
 
     IT MUST NOT BE USED BY ANYBODY ELSE FOR ANY OTHER PURPOSE WITHOUT
     CONTACTING THE FILE PRODUCER.
 
 
Pedigree
--------------------------------------------------------
 
     This file was created from data in the STAT tool input data files
     provided by Rene Pischel, DLR on October 19, 2000. The following steps
     were followed in the process of creating this file:
 
        -- STAT input files "longlatfile2.txt" and "orbitparam.txt" were
           merged together to obtain list time-tagged orbital elements;
 
        -- this SPK made from the list of time tagged elements data
           using MKSPK program.
