About:

Pyxrr is another tool for simulation of X-ray reflectivity curves. It is programmed in Python and C and the sources are completely open. The calculation is based on a rather simple model and runs pretty quickly. It's especially useful for fitting of large sets of data, large number of layers and also simultaneous fitting of multiple measurements of the same sample (e.g. taken at different energies). Another advantage is that it naturally allows scipting and batch processing in Python. Multi-core processing is implementet in the C subroutines and it is platform independent. However, No detailed documentation is given yet, and there may still be some bugs. Please feel free to contribute.
