Ah, I see -- yes, you don't need it if you've already decomposed the depth 
into radial slices. What I mean is that the index 'i' can either denote a 
slice/depth range, or some polynomial basis function. In the former case, the 
(radial-direction) basis you are using just happen to be piecewise constants.
