It will not be of much use, since I don't know of any prediction program
that can handle a hyperbolic type orbit (e>1)
There are some integrator programs that work on X,Y,Z,Xdot,Ydot,Zdot
initial position/velocity (?)
But the best alternative is SkyMap's Rocket trajectory - it needs a file
of lat./lon./height values, preceded by time in seconds from some given
(map) Epoch time.
RA/Dec./Range values can easily be converted, but I didn't try it for the
probe that passed before New Year, because the distance values were
given with 0.001 AU "precision" (and quite distant!)
