QREFGEN

This program is a utility for producing sets of possible wave vectors for several quasicrystal space groups. It is possible to constrain the theta range and the maximum internal component qi . The program also tries to obey the corresponding reflection conditions. The criteria for that are based on the following two papers: (1) A.Yamamoto: Crystallography of Quasiperiodic Crystals, Acta.Cryst.(1996), A52,509-560; (2) Rabson, Mermin, Rokshar, Wright: The space groups of axial crystals and quasicrystals, Rev.Mod.Phys.(1991), Vol.63,No.3,699
