```
public Vector3D getEccentricities()
```
    Get the phase center eccentricities.
    
    Returns:
    
    phase center eccentricities (m)
  - getPhaseCenterVariationFunction
```
public PhaseCenterVariationFunction getPhaseCenterVariationFunction()
```
    Get the phase center variation function.
    
    Returns:
    
    phase center variation function (may be null if phase center does not depend on signal direction)
