DESCRIPTION¶
usage: pyFAI-waxs [options]
-p ponifile file1.edf file2.edf ...
Azimuthal integration for powder diffraction.
positional arguments:¶
- FILE
- Image files to integrate
optional arguments:¶
- -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
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.
