Approximate Time Coverage
 
        From: 1998 JAN 01 00:00:00.000 (TDB)
        To  : 2010 JAN 01 00:00:00.000 (TDB)
 
 
Status
--------------------------------------------------------
 
     This is the current best estimate for the position of Saturn's
     minor satellite Pan as of 2-May-2000. Currently, no formal updates
     to this ephemeris are planned. However, if you need a more recent
     ephemeris and have reason to believe that observations following
     the creation date of this ephemeris may significantly improve the
     positional knowledge for Pan, we recommend that you contact NAIF
     and to the extent that resources are available we will attempt to
     provide an update to this ephemeris.
 
 
Production/History of this Ephemeris
--------------------------------------------------------
 
     This ephemeris was produced by Bill Taber of the Navigation Ancillary
     Information Facility (NAIF) at the Jet Propulsion Laboratory on
     2-May-2000 for general use. It was transformed to SPK format from a
     equinoctial elements provided by Bob Jacobson of the Solar Systems
     Dynamics group of the Astrodynamics and Navigation section (section
     312) of the Jet Propulsion Laboratory.
 
     The Release Form for the ephemeris description of these satellites is
     included as an appendix at the end of this note.
 
 
Usage
--------------------------------------------------------
 
     To determine the state of Pan with respect to any object other than
     the Saturn barycenter, you need at a minimum a planetary ephemeris. It
     is recommended that you use JPL developmental ephemers 403 (DE403) or
     later when computing states of these satellites with respect to
     anything other than the Saturn Barycenter.
 
     DE403 is available via anonymous ftp on NAIF's ftp server: naif-sun
     (ip address 128.149.126.11) in the directory
     pub/naif/generic_kernels/spk. Both binary and transfer format
     ephemerides are available. They are in the files.
