The Voyager 2 Uranus flyby trajectory file:

  vgr2.u00002.nio  ("Far Encounter" period)

was produced by R. Jacobson of JPL's Solar System Dynamics Group
at JPL. It results from Jacobson's reprocessing of radio and
optical data obtained during the Voyager 2 flyby of Uranus.

Accuracy of this trajectory is unknown, other than the presumption
that it is better than all previously made orbit solutions for
Voyager 2 at Uranus.

Jacobson is doing still more work on this trajectory; a better
solution is expected later in 2007.
