Interface IERSConventions.NutationCorrectionConverter

  • Enclosing class:
    IERSConventions

    public static interface IERSConventions.NutationCorrectionConverter
    Interface for functions converting nutation corrections between δΔψ/δΔε to δX/δY.
    • δΔψ/δΔε nutation corrections are used with the equinox-based paradigm.
    • δX/δY nutation corrections are used with the Non-Rotating Origin paradigm.
    Since:

      • toNonRotating

        double[] toNonRotating​(AbsoluteDate date,
                               double ddPsi,
                               double ddEpsilon)
        Convert nutation corrections.
        Parameters:
        date - current date
        ddPsi - δΔψ part of the nutation correction
        ddEpsilon - δΔε part of the nutation correction
        Returns:
        array containing δX and δY
      • toEquinox

        double[] toEquinox​(AbsoluteDate date,
                           double dX,
                           double dY)
        Convert nutation corrections.
        Parameters:
        date - current date
        dX - δX part of the nutation correction
        dY - δY part of the nutation correction
        Returns:
        array containing δΔψ and δΔε
