rtImagePSFFieldHeight

 Not functional yet - or perhaps implemented elsewhere.

 1.  Plot PSFs as a function of field height
 
 foo = [];
 for ii=1:12
     foo = [foo, rt.psf.function(:,:,ii,10)];
 end
 
 imshow(foo)
 
 
 2.  Show the interpolated distortion image (not with wavelength) but with 2D pixDistUnit
 kind of surf plot.
 
 
 3.  Get rid of the darn black line.
