This document describes XtcExplorer V00-01-1516

This is a description and documentation of a GUI tool to explore the xtc data. It is written in python, relying on PyQt4 for graphical user interface. The data processing is done via the pyana framework and visualization provided by matplotlib. It can be run on any xtc file, including the file being written during data aquisition (DAQ).

CsPad image where the region of interest (a red rectangle in the left figure) has intensity above a given threshold. The right image shows the region of interest.

CsPad image where region of interest (red rectangle) has intensity above a given threshold. Additionally, a dark-subtracted image is shown (bottom left), where the dark average is based on below-threshold shots from the same run (shown bottom right.

This image is similar to the one above. The intensity limits have been adjusted interactively.

At the end of the job, the average of good images (left) and rejected / dark images (right) is shown.

Image from two Pulinx cameras, no filtering or background subtraction. Projections in x and y are shown.

Displays of three different Pulnix TM6740 images of YAG screens, after rotation/translation. Also shown, differences between images and FFT of differences.

Display of images from Princeton camera. Plotted at end of job of average images above threshold, and average images below threshold (dark). A red rectangle shows the region of interest that was used to evaluate intensity w.r.t. threshold. Configuration: 'threshold = 350 (700:800,1100:1200)'
