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=12.398419292keV.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
