DE118/DE200 ephemeris
N-body numerical integration of the Moon and planets uses either 80-bit extended real or 64-bit arithmetic. Physics model includes oblateness of the Earth and Moon, Earth tides, Lunar librations, relativity corrections, and 5 asteroids. With 80-bit support it reproduces the Jet Propulsion Laboratory's DE200 ephemeris to an extremely high precision. C source program tested on Windows, MSDOS, VAX, Sun, 680x0. Version de118i-2 works with the gcc-3.4 compiler. It also has build scripts for Microsoft Visual C++ and Borland C++ Builder. Extra user-defined bodies, such as asteroids, can be included.
