Rietveld Patterns in the PDF

     The issue of how (or whether) to include Rietveld patterns in the PDF 
     has caused a lot of heated discussion at the ICDD meetings, and the 
     current state may be the "least unsatisfactory" one.
     
     My personal opinion (not shared by many others) is that the peak 
     positions and intensities derived from a profile fit (either with or 
     without a structure model) represent the best estimate of what is 
     really in the pattern - the reflections are there no matter how we 
     describe them.  When using a structural model, the Fobs derived from a 
     profile fit are "biased" by the model, but so what?  They're still 
     better than any other measure I know.
