    Description copied from class: SpectralCurve
    
    This function determines the actual spectral curve data. Note that the lambda parameter is assumed to be in nanometers.
    
    Specified by:
    
    sample in class SpectralCurve
    
    Parameters:
    
    lambda - wavelength to sample in nanometers
    
    Returns:
    
    the value of the spectral curve at this point
  - get
```
public static final XYZColor get(float x,
                                 float y)
