% The matrix that rotates from the Earth mean axes to the true axes. See also NutDelta, ObOfE. Default is today's date. -------------------------------------------------------------------------- Form: [n, eps0, epsT, deltaPsi, deltaEps] = EarthNut( T ) -------------------------------------------------------------------------- ------ Inputs ------ T (1,1) Julian centuries of 86400s dynamical time from j2000.0 ------- Outputs ------- n (3,3) Nutation matrix (transforms from mean to true) eps0 (1,1) Mean obliquity (deg) epsT (1,1) True obliquity (deg) deltaPsi (1,1) Delta in longitude (deg) deltaEps (1,1) Delta in obliquity (deg) -------------------------------------------------------------------------- References: Seidelmann, P., ed.
