Owl is a Python software tool for visualisation of diffraction patterns and other data related to diffraction experiments saved in the CXI File Format.

An experimental diffraction pattern together with a ball diffraction model of similar size and intensity.

This versatile visualisation tool provides many helpful features, such as sorting and filtering of diffraction patterns, side-by-side viewing of data and model, on-the-fly computation of patterson image and selective tagging of patterns.

The development of Owl can be followed on Github. The code is available under the GNU General Public License.
