Hi Larry,

Confound it... I should have read your message more carefully, in
particular the part where you state quite clearly that you've entered
Steve Preston's data.

If you've done that, then you should indeed get _exactly_ the
correct position for Juno. In fact, you should be able to replicate
the occultation path Steve would get; a while back, he ran some tests
and found that Guide and OCCULT (his software of choice) agree to within
the margins of error of each program.

So, I'll assume you've double-checked the orbital elements and they
look okay. Next, I'd check to make sure that the date and time for
your test case is correct (including time zone), and that your "home
planet" is the Earth and not the Moon (they are just far enough apart to
make a multi-arcminute error possible).

I can be pretty sure the error isn't due to your position on the
earth; that wouldn't cause anything resembling a seven-arcminute error.

My apologies for the earlier e-mail; I was so sure that I'd found
the problem that I leapt to a conclusion. Foolish of me...
