This collection of ten text files was created by Acton on 5/23/99,
using ssc and the vg1_jup.bsp and vg2_jup.bsp SPK files. Also used
naif0007.tls and "pck_jup_special.tpc", which is a modified version
of pck0006.tpc with Jupiter's Wo term set to 0.0 and much other
data removed.

They were made for Constantine Thomas, of the Planetary Science
Research Group, Environmental Science Dept., Lancaster University,
England, UK. He is preparing Voyager flyby animations for the two
Jupiter flybys.

Previous data files made for him gave:

(1) time, position and range in the J2000 frame

(2) time, position and range in the "IAU_JUPITER" rotating frame

Neither of the above two were what he wanted.
