I am querying what available software might be available that will analyse powder diffraction data out to high Q (Q>20) for looking at PDFs/local order? Possible programs would most like have to do some(all?) of the following: Correct the XRD data for absorption, polarization, multiple scattering, background scattering, Compton scattering, Normalise the corrected XRD data into absolute (electron) units, Calculate the PDF (atomic distribution function/radial distribution function) by Fourier transform of the corrected and normalised data. ====== Thanks in advance, Lachlan. -- Lachlan M.
