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:
6.1
