Integration tool: pyFAI-saxs
============================

Purpose
-------

Azimuthal integration for SAXS users.

pyFAI-saxs is the SAXS script of pyFAI that allows data reduction (azimuthal integration) for
Small Angle Scattering with output axis in q space.

Usage:
------

pyFAI-saxs -p=param.poni -w1.54 file.edf file2.edf file3.edf


Options:
  -h, --help            show this help message and exit
