Does anybody have the source code to one of the more accurate
software almanacs? I wrote one myself, but it differs from
the Nautical Almanac by up to 10 arcminutes in many cases.

I'm trying to do it with pencil & paper. If I wanted to use a computer,
I'd get a GPS receiver.
(Actually, I use a computer to generate pages from the sight reduction

answers, but that's it.)
