IERSConventions.NutationCorrectionConverter (OREKIT 12.2 API)

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.
