public TwoDVariation(double polarStart,
                     double polarStep,
                     double azimuthStep,
                     double[][] variations)
```
    Simple constructor.
    
    Parameters:
    
    polarStart - start polar angle
    
    polarStep - between grid points
    
    azimuthStep - step between grid points
    
    variations - sampled phase center variations

```
public double value(double polarAngle,
                    double azimuthAngle)
```
    Evaluate phase center variation in one signal direction.
    
    Specified by:
    
    value in interface PhaseCenterVariationFunction
    
    Parameters:
    
    polarAngle - angle from antenna axial direction (zenith angle for receiver antennas, nadir angle for GNSS satellites antennas)
    
    azimuthAngle - angle around axial direction
    
    Returns:
    
    phase center variation in the signal direction (m)
