\* Coordinate Transformations
\* Planetary Positions Mercury - Pluto (Mercury - Neptune using VSOP87)
\* Planetary Magnitude, illuminated disk and phase angle.
\* Lunar Position (using ELP82), phase angle.
\* Elliptic Motion of bodies (Asteroid + Comet positional and orbit data)
\* Asteroid + Comet magnitudes
\* Parabolic Motion of bodies (Comet positional data)
\* Orbit velocities and lengths
\* Atmospheric refraction
\* Rise, Set and Transit times.
\* Semidiameters of the Sun, Moon, Planets and asteroids.
