Fast Azimuthal Integration

• SPD which is a large piece of C-code dealing with image corrections and azimuthal integration, mainly written by Peter Boesecke and Rainer Wilcke
• Execution tests written in python to ensure the equivalence of the results obtained after integration by different software like FIT2D, SPD or XOP, this is written in python.

pyFAI is a python library for Fast Azimuthal Integration. It may appear surprising that a python project is called "Fast" in a world where most other software are written in C or Fortran. It simply means that the integration is done by a single operation which leads an input pixel on the detector to a contribution to a diffraction pattern (without re-sampling or aliasing, ...), allowing optimization on this single algorithm and optimization of it's implementation (Cython, port to GPU, ...), and leaving the flexibility of python for everything else.
