Path: Orbit/OrbitCoord
% Transformation matrix from ecliptic to Sun-Earth rotating frame. This is a single rotation about the z-axis. If the JD is not input it will use the ecliptic longitude for J2000.0. Since version 2014.1 -------------------------------------------------------------------------- Form: c = CEcl2SER( jD ) -------------------------------------------------------------------------- ------ Inputs ------ jD (1,1) Julian date ------- Outputs ------- c (3,3) Transformation matrix from the heliocentric frame with xy ecliptic plane to Sun-Earth rotating frame, with x along Sun-Earth line, y orthoganal to xz plane. --------------------------------------------------------------------------
