Integration tool: pyFAI-waxs
============================

Purpose
-------

Azimuthal integration for powder diffraction.

pyFAI-waxs is the script of pyFAI that allows data reduction (azimuthal integration) for
Wide Angle Scattering to produce X-Ray Powder Diffraction Pattern with output axis in 2-theta space.

Usage:
------
pyFAI-waxs -p param.poni [options] file1.edf file2.edf ...

Options:
--------

**-h**, **--help**
   show this help message and exit

**-v**, **--version**
   show program's version number and exit

**-p** PONIFILE
   PyFAI parameter file (.poni)

**-n** NPT, **--npt** NPT
   Number of points in radial dimension

**-w** WAVELENGTH, **--wavelength** WAVELENGTH
   wavelength of the X-Ray beam in Angstrom

**-e** ENERGY, **--energy** ENERGY
   energy of the X-Ray beam in keV (hc=12.398419843320026keV.A)

**-u** DUMMY, **--dummy** DUMMY
   dummy value for dead pixels

**-U** DELTA_DUMMY, **--delta_dummy** DELTA_DUMMY
   delta dummy value

**-m** MASK, **--mask** MASK
   name of the file containing the mask image

**-d** DARK, **--dark** DARK
   name of the file containing the dark current

**-f** FLAT, **--flat** FLAT
   name of the file containing the flat field

**-P** POLARIZATION_FACTOR, **--polarization** POLARIZATION_FACTOR
   Polarization factor, from **-1** (vertical) to +1 (horizontal),
   default is None for no correction, synchrotrons are around 0.95

**--error-model** ERROR_MODEL
   Error model to use. Currently on 'poisson' is implemented

**--unit** UNIT
   unit for the radial dimension: can be q_nm^-1, q_A^-1, 2th_deg,
   2th_rad or r_mm

**--ext** EXT
   extension of the regrouped filename (.xy)

**--method** METHOD
   Integration method

**--multi**
   Average out all frame in a file before integrating extracting
   variance, otherwise treat every single frame

**--average** AVERAGE
   Method for averaging out: can be 'mean' (default), 'min', 'max' or
   'median

**--do-2D**
   Perform 2D integration in addition to 1D

pyFAI-waxs is the script of pyFAI that allows data reduction (azimuthal
