public class MeeusSun
extends AbstractIAUCelestialBody

This class implements the Sun ephemerides according to the algorithm of Meeus, it only provides the position. Note that it is not possible to build this Sun from the CelestialBodyFactory.

See "Astronomical Algorithms", chapter 24 "Solar Coordinates", Jean Meeus, 1991. This class allows the use of three different Meeus model : the standard Meeus model, the STELA one and the on board model (used for CERES mission for instance).

Note that pole information allowing to define inertially-centered frame and rotating frame are defined in IAUPoleFactory since Meeus model does not provide the information.
