I know the early references (Loopstra et al) to pryolytic graphite as a filter for 2.6A neutrons, but want to filter higher energies of ~3A eg. by reflecting just the specific 1.5A and 1A harmonics using highly oriented PG like a secondary monochromator-filter as was tried at ILL on IN14. Does so

Dear list members, We have been refining some synchrotron X-rays diffraction data collected at constant steps in Q space using GSAS. But due to some funny peakshapes I would like to change to FULLPROF, where more flexible peakshapes are available. But FULLPROF is not accepting data other than cons
