  • source (default: "CxiDs1.0:Cspad.0") – source of data,
  • key (default: "") – key for data processing stage,
  • imgkey (default: "Image2D") – output key for image saved in event,

    )
    • - calib pars,
    2 bit (
    • +2
    )
    • - consumed time
    /
    • per event.

Remarks:

  • By default the key corresponds to raw data.
  • If the imgkey is defined as "Image2D", the image is saved in the event as a CSPadPixCoords::Image2D<double> object, otherwise (for other names) as a ndarray<double,2> object.

Other event with better subtracted background:

Module ImgAlgos::ImgRadialCorrection

This module averages the image pixel amplitude in r-phi bins, normalizes it per single pixel and subtracts the average amplitude from each pixel. Image is obtained from event by its source and inkey values. The output corrected image is saved in the event with outkey keyword. Carthesian to polar coordinate transformation is done with respect to center coordinates xcenter, ycenter. The central region (r<rmin) and edges of the image (r>rmax) pixels can be removed from further consideration by setting rmin and rmax. The number of radial bins is defined as an int(rmax-rmin). The number of angular bins is set by n_phi_bins.

Module configuration parameters:

  • source (default: "DetInfo()") – input source of data
  • inkey (default: " " ) – key for input data, by default use raw data
  • outkey (default: "rad_corrected" ) – output key for further image processing
  • xcenter (default: 850) – x coordinate of the image center
  • ycenter (default: 850) – y coordinate of the image center
  • rmin (default: 10) – radius minimal image is not processed for r<rmin
  • rmax (default:1000) – radius maximal image is not processed for r>rmax
  • n_phi_bins (default: 12) – number of angular sectors for the background averaging.
  • event (default: 0) – test event for print/save
  • print_bits (default: 0) – module verbosity:
    • =0 - print nothing,
    • +1 - input pars,
    • +2 - summary,
    • +4 - event ID,
    • +8 - info about input image type (ndarray<double,2> or Image2D<double>).
