UMWEG -98: a program for calculation and graphical representation of multiple diffraction patterns

UMWEG-XX was designed as a software tool for taking into account multiple diffraction effects in many areas of crystal structure analysis. The UMWEG-98 version of the program makes possible the calculation and graphical representation of multiple diffraction patterns (Renninger scans, multiple diffraction peak location plots) of forbidden and weak reflections and can be applied to synchrotron as well as K[alpha]1,2 radiation. The program is written in standard Fortran90 and may be ported to Unix platforms, such as HP, Sun, Silicon Graphics and IBM, as well as to DOS and Windows platforms. The program runs without any commercial subroutine libraries. Consequently it can be used without licence problems. A current version is distributed via http://www.rrz.uni-hamburg.de/mpi/rossmanith. Executable (binary) files are available free of charge for academic use only
