With a few exceptions, the file segments used to make this SPK file
are those parts of individual files based on orbit determination
observables (Doppler and/or OPNAVS).  The time span of the observable data is
listed under 'COMMENTS'.

The period of this file covering the Shoemaker-Levy Comet (14-JUL-1994
to 22-JUL-1994) does not contain the comet fragments.  Use file
SL994-07-15.BSP for those bodies.

ET is used to denote ephemeris time; it differs from UTC (universal time
coordinated) in which spacecraft events are usually given by the following:
ET minus UTC = 56.184 sec (01-Jan-1988)
= 57.184 sec (01-Jan-1990)
= 58.184 sec (01-Jan-1991)
= 59.184 sec (01-Jul-1992)
= 60.184 sec (01-Jul-1993)
= 61.184 sec (01-Jul-1994)
SCLK is spacecraft clock string.

This file was created with NAIF Version 45 software.

NOTE:  This file DOES NOT contain the Shoemaker-Levy Comet Fragments (use
file SL994-07-15.BSP for those bodies).
The final probe (SPICE Body ID -344) trajectory is available in file
S960730A.BSP or S960730A.TSP.
For a continuation of the Galileo trajectory, use the current tour file.
The tour file is updated twice per orbit during the orbital tour.  The
first portion (up to the approximate date the file was created) will be
based on reconstruction and the remaining portion will be our current
expected trajectory.  It will always begin on 01-JUL-1995 00:00:00.00 UTC.
To date (13-DEC-1996) three tour files have been delivered to the GLLSVC;
these will be replaced by subsequent deliveries and will always contain the
reconstruction portion of the preceding file:
S960910A.BSP
S961004A.BSP
S961107A.BSP
