Aren't f an g both analytical functions or am I missing somehing here? 
Fourier (Warren-Averbach) analysis does not assume any profile shape. That is 
why it's often so cumbersome. As soon as one assigns a function to the 
profile, the plot of Fourier coefficients is always smooth and beautiful (but 
questionable, of course). Doesn't simplification already set in at this point 
if one goes the Rietveld route?
