Path: Interplanetary/InterplanetaryOrbit
% Compute the phase angle in the ecliptic plane of a given planet at jD. Uses PlanetPosJPL for ephemeris. -------------------------------------------------------------------------- Form: theta = PlanetHelioPhase( kPlanet, jD ); -------------------------------------------------------------------------- ------ Inputs ------ kPlanet (1,1) Index of planet (e.g. 3 is Earth) jD (1,1) Julian date ------- Outputs ------- theta (1,1) Phase angle of planet in x-y (ecliptic) plane --------------------------------------------------------------------------
