Next message: George Huxtable: "Re: GMT from Jupiter's moons"
This is more of a surveying problem rather than a marine navigation
problem, and primarily of historical interest, but....
All the ephemerides I have seen for occultations of Jupiter's moons are
timed to the minute. I have not seen tables for occultation of stars
by the moon. Was one minute the limit of resolution for determining
GMT in the old days or could averaging of numerous observations give a
more accurate determination of Greenwich time?
Thanks,
Fred
