 
 
Description:
------------
 This trajectory is based on orbit solution JPL#K051/17. The solution is based
 on data spanning 2003-Oct-01 to 2005-Jul-04, including approximately 4000
 optical navigation images from the Deep Impact Spacecraft ending
 2005-Jul-04 05:56:16.660 (about 12 minutes after the impact at 05:44:36 UTC).
 
Limitations:
------------
 Time span covered is 2000-Jan-1 to 2050-Jan-1, but this solution is likely
 to degrade in accuracy as time from the 2005 encounter increases. Therefore,
 for non-encounter studies, a different solution from the JPL orbital-elements
 database should be used.
