And now, how different are the Rietveld populations
in the ICSD database (release 1998-1) :
REM = RVP : 5925 entries (Rietveld refinement)
REM = XDP : 6698 (X-ray powder)
REM = NDP : 5585 (neutron powder)
REM = SNP : 183 (synchrotron powder)
Combinations :
RVP+NDP = 3276 entries (Rietveld + neutron)
RVP+XDP = 2557 entries (Rietveld + X-ray conventional)
RVP+SNP = 126 entries (Rietveld + synchrotron radiation)
The authors populations are very distinct and can be seen at :

http://pcb4122.univ-lemans.fr/icsd/icsdrxdp.txt (RVP+XDP)
http://pcb4122.univ-lemans.fr/icsd/icsdrsnp.txt (RVP+SNP)
Some love neutrons, others love X-ray, some love both,
few prefer synchrotron (but this last population is increasing
fast).
