Hal, do you have a link to somewhere that has the NOVAS code?

Thanks,

You should look at the US Naval Observatory's "NOVAS" code (C and
Fortran source available), and Jean Meeuse's "Astronomical Algorithms"
book. Those two sources will get you 90% of the way there (take it
from one who's done it!). For the remaining 10%, hope you were paying
attention in your math classes Actually, there's a published
"Explanatory Supplement" to the nautical almanac (jointly published by
the same two hydrographic offices that do the nautical almanac) which
contains a good bit of (quite technical) exposition. I've also found
Charles Cotter's book "History of Nautical Astronomy" quite useful
(out of print, but in many libraries). I may be mangling these titles
a bit, but I'm sure of the authors.
