True Nick,
actually I implemented the size and strain distributions (both) in my Rietveld code (Maud) and I demoed it in Praha beginning of September. Actually the program was not released and it is still under testing because I changed also the interface and other parts that needed more work; but this new version will be ready soon for the public.
Indeed I tried the size and strain distributions model on some samples and on the SSRR data. In some cases it does not really matter using distributions respect to other mathematical functions, but in few cases I got a dramatic improvement in the fitting with the distributions method. Residuals become flat! Rw really low.....
I hope to get a version ready for the public in one or two weeks, not too much work to do, but not too much time also, so everyone willing to try it can do it.
Actually I forgot to mention, for who does not know it, Maud already contains also anisotropic size and microstrain (Popa model ;-)) ) and the size-strain part is separated from the instrumental broadening as it should be for size-strain analysis. The distributions and anisotropy models can be used together also.....
best regards,

Good answer Davor, but why you are avoiding to say that if the size profile
(15a, 21, 22) from JAC(2002)35, 338-346 (used in 3.1 of RR paper) would be
implemented in the Rietveld codes these codes would become much "powerful"
and with a wider application in the size distribution determination?
