This page provides examples for selected modules from Psana Module Catalog. Only the modules that are included in the standard analysis releases appear on this page.

Example for Package ImgPixSpectra

Modules:

• ImgPixSpectra::CSPadPixSpectra
• ImgPixSpectra::MiniCSPadPixSpectra
• ImgPixSpectra::CameraPixSpectra

Auxiliary scripts

A few python scripts in ImgPixSpectra/data/ show how to process/plot the spectral array stored in the file.

• PlotSpectralArrayFromFile.py - allows to plot content of the spectral array as a 2-d plot. For example, the command code

  
  ImgPixSpectra/data/PlotSpectralArrayFromFile.py mini-cspad-pix-spectra.txt
  

  generates image for limited range of pixels for CSPad, MiniCSPad, or Camera
• , respectively:
  Image RemovedImage Removed Image RemovedSpectralArray.py - provides access to the spectral array stored in the file. The class SpectralArray defined in this script is used in the PlotSpectralArrayFromFile.py.

...

• psana.cfg - set non-default parameters to run psana for ImgAlgos::ImgPeakFinder and ImgAlgos::ImgPeakFilter
  The psana running this script saves images and peaks for event 115 in text files.
• PlotCameraImageFromFile.py - Plots image and spectrum for image saved in file.
• PlotCameraImageAndPeaks.py - Plots image with found peaks and spectrum.

• ImgPixSpectra::CameraPixSpectra

The command for auxiliary script:

ImgPixSpectra/data/PlotSpectralArrayFromFile.py mini-cspad-pix-spectra.txt

generates image for limited range of pixels for CSPad, MiniCSPad, or Camera, respectively:
