Crystallographic toolbox and library
copied from cf-staging / xfabxfab is an open source python package for crystallography and xray diffraction analysis. xfab was originally a python library for the totalcryst program with crystallographic computations inside, mostly written by Henning Sorensen and Jette Oddershede at Riso. Today xfab is maintaned by the GitHub FABLE-3DXRD organization who maintain many open source libraries for crystallography and diffraction analysis.
