      • calcSNom

        public static double calcSNom​(double xi,
                              double precRate)
        Calculates the nominal speed of the z axis in solar motion units, as function of the precession rate precRate [rev/yr] and the solar aspect angle xi [rad]. This method implements Eq. (26) in FM-037-2, accurate to O(1/K^12).
        Parameters:
        xi - solar aspect angle [rad]
        precRate - precession rate [rev/yr]
        Returns:
        nominal speed (S)
