Pedigree
--------------------------------------------------------
 
     The original files used to create this SPK file contained numerically
     integrated orbits for some of Saturn's satellites. This file
     was designed to be used for science planning purposes. For more
     information, see Appendix 1 of these comments.
 
 
Usage
--------------------------------------------------------
 
     The PCK file "cpck_rock_10Jan2005_merged.tpc" should be used with this file.

Summary:  Numerically integrated orbits for Methone (S/2004 S 1) and Pallene
    (S/2004 S 2).  The orbits are fit to data from 77 and 51 Cassini images,
    respectively.  The latest Methone image was on 7 March 2005 and the
    latest Pallene image was on 28 February 2005.  We also included the
    Voyager 2 observation of Pallene, originally identified as S/1981 S 14.
