This program uses information from case.struct (lattice type, atomic positions). If NSYM was set to zero it generates the space group symmetry operations and writes them to case.struct_st to complete this file. Otherwise (NSYM > 0) it compares the generated symmetry operations with the already present ones. If they disagree a warning is given in the output. In addition the point group of each atomic site is determined and the respective symmetry operations and LM values of the lattice harmonics representation are printed. The latter information is written into case.in2_st, while the local rotation matrix, the positive or negativ IATNR values and the proper ISPLIT parameter are written to case.struct_st. (See appendix A and Sec. 4.3).
