Steven,

I expect to make good use of your Precomputed Lunar Distance Tables. They cut
the work of a lunar distance by more than half. You've done us lunarians a
great service.

But for the sake of those who are also using my Tables for Clearing, there
should be a warning. The three-hour interval can't be proportioned with tables 7
and 8. Not without a bit of fancy footwork, anyway. Since I can't put a
warning in the copies of my tables that are out there, I hope you'll put a warning
in YOUR tables.

Also, it would be nice to have a proportional log table people could print
off at the same time they print your Precomputed Distances. A prop log table
would make things even more handy, since you already give, alongside the
distance, the first of the three that will be needed.

Sometime, I hope you'll consider expanding your Tables to a one-hour
interval. I'd happily pay $20 or so for a copy. With a three hour interval those short
distances can have ferocious second difference problems. Nine times as bad as
for one hour.

Bruce
