X0h Web interface to compute crystal susceptibilities for medium-energy X-rays (0.1–10Å) for some crystals. Also provides the Bragg peak halfwidth, extinction and absorption lengths. Uses International Tables for f' and f" and interpolates them for intermediate wavelengths with the help of algorithm. Results must be treated with care in a close vicinity of absorption edges.

XRD2DScan Tool for displaying and analyzing two-dimensional (2D) X-ray diffraction patterns collected using a diffractometer equipped with a 2D or area detector. Can find the direct beam or the pattern center even when detector is at a angle different from zero. It can calculated different types of scans, also work in batch mode to analyse many data files.
XRDA XRDA 3.1 is meant to accomplish the complete handling and analysis of X-ray diffraction data, recorded in either the energy-dispersive or angle-dispersive mode. The analysis per se is done following six major steps: (1) peak profile fittings using preset common profile functions or user-defined profile functions (2) organization of X-ray diffraction lines under different groups (phases) if a pattern is one of a multi-phase sample (3) assignment of Miller indices to the fitted lines (4) definition of the Bravais lattice and the atomic positions for each phase as required (5) lattice parameter fitting and diffraction intensity calculation.
