Unit cell parameters can be edited on-the-fly to see how peak splittings change. Pepinsky's Machine Both a teaching aid to illustrate the principles and the application of the Fourier series in crystallography, and a research tool to permit the systematic calculation of permutation syntheses for all centrosymmetric plane groups.
