This plugin integrates 2D detector images in azimuthal (Figure 1) or radial (Figure 2) direction using Fit2D.

Figure 2 Left: Azimuthal plot. Right: Scheme of the binning (red dashed line) in radial direction.


Parameter

  • Profile: Radial for a radial plot (Figure 1) or Azimuthal for a azimuthal plot (Figure 2).
  • Pixel Size, Beam Center, ...: For all parameters concerning the integration with Fit2D refer to Fit2D Reference Manual.
  • Mask File (optional): ... Choose a Fit2D mask file to let Fit2D exclude areas on integration process.
  • Dark Current (optional): Choose a detector image file that should be subtracted from the sample image before integration.
  • Empty Beam (optional): Choose an empty beam image

Inputs

  • image: The path to the detector image.

Outputs

  • x: q values if Profile is set to Radial, chi values if Profile is set to Azimuthal.
  • I: The integrated intensity data.
  • I_eb: The integrated empty beam if an empty beam image was specified in the parameters. Otherwise an array of zeros.
