SIMREF SIMPRO is a program for SIMultaneous Rietveld REFinement with multible powder datasets. The most important features of the program are: Refinement of multible datasets from X-ray (tubes), synchrotron and neutron diffractometers Refinement of multible phases Refinement of modulated structures with symmetry adapted displacement vectors Calculation of powder patterns, structure factors and hkl lists Lorentz polarisation and geometry factors for different diffractometers Different peak shape functions Peak-shift correction by fitting a second-order polynomial in 2theta Scaling the 2theta values on standards: the lattice constants of silicon in the whole temperature range up to 1500 K are built in Background fitting with a 6th-order polynomial or fixed values Individual weight scheme for each data set The Goodness-of-fit is given by Nsigma (J. Ihringer, 1995). Calculation of distances after the refinement
