Typical values of Rietveld instrument profile coefficients

GSAS instrument parameters are tabulated for a variety of laboratory and synchrotron diffractometers to give users an idea of the typical ranges of profile parameters when they generate their own instrument parameter files. For modern high-resolution laboratory diffractometers, the parameters fall in the ranges 0<3, V=0, 0<4. 1<3. 0<3, 1<3, and 0
