xrayutilities
xrayutilities is a collection of scripts used to analyze and simulate x-ray diffraction data. It consists of a Python package and several routines coded in C. For analysis the package is especially useful for the reciprocal space conversion of diffraction data taken with linear and area detectors. For simulations code for X-ray reflectivity, kinematical and dynamical diffraction simulation of crystal truncation rods as well as fundamental parameters powder diffraction is included.
