Per your request:

Tom Metcalf (metcalf at milo.IFA.Hawaii.Edu) responded with:

"Get a book called "Astronomical Algorithms" by Jean Meeus.  It's
published by Willmann-Bell Inc., P.O. Box 35025, Richmond, Virginia, 23235."

Since I have to borrow the book through Interlibrary Loan and don't have it
yet, that's all I can tell you.
