# check\_calib(1)

DEPRECATED tool that checks a calibratation at the sub-pixel level

## NAME

check\_calib - DEPRECATED tool that checks a calibratation at the sub-pixel level

## DESCRIPTION

usage: check\_calib \[options\] **-p** param.poni image.edf

Check\_calib is a deprecated tool aiming at validating both the geometric calibration and everything else like flat-field correction, distortion correction, at a sub-pixel level. Note that \`check\_calib\` program is obsolete as the same functionality is available from within pyFAI-calib, using the \`validate\` command in the refinement process. :returns: True if the parsing succeed, else False

### positional arguments:

- FILE

  Image file to check calibration for

### options:

- **-h**, **--help**

  show this help message and exit

- **-V**, **--version**

  show program's version number and exit

- **-v**, **--verbose**

  switch to debug mode

- **-d** FILE, **--dark** FILE

  file containing the dark images to subtract

- **-f** FILE, **--flat** FILE

  file containing the flat images to divide

- **-m** FILE, **--mask** FILE

  file containing the mask

- **-p** FILE, **--poni** FILE

  file containing the diffraction parameter (poni-file)

- **-e** ENERGY, **--energy** ENERGY

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

- **-w** WAVELENGTH, **--wavelength** WAVELENGTH

  wavelength of the X-Ray beam in Angstrom
