On further reflection I suspect the important parameter in this
measurement is the radial gradient of Jupiter's gravitational
field. The Shapiro delay will be different for different radio
antennae at different global locations. A picosecond is about
0.3 mm (expressed in terms of length), emphasizing what a tough
measurement this will be!

Papers in the preprint archive can be reached through
http://xxx.lanl.gov. Search by author (Kopeikin in this case)
in the appropriate category or categories (I used astrophysics,
physics, & gr-qc). Once you learn to use this resource you'll
check it frequently, if not daily.
