Full Profile PDF fitting using PDFFIT

• We extract information from the PDF by fitting structural models to the data

• We use Full-profile least-squares fitting of the PDF using the program PDFfit

• The red line is the PDF from the model, the blue line the data, the green line the difference.

• The data are neutron data from LaMnO3 collected 10K at IPNS, Argonne National Laboratory, IL.
