Does anyone know where I can get an algorithm (and/or code) for calculating ephemerides (tables of the apparent positions of the planets and the moon)? While I understand most of the basic underlying astrodynamic principles, I know there are some programs in use which are plenty accurate for my uses and I do not want to bother developing a program which already exists. Please respond to ihuxl!rjnoe Roger Noe
