- If a threshold is provided, shots above threshold will be displayed / stored, and shots below
threshold will be added to sum of darks for averaging. - If a dark file is provided, background subtraction is done before filtering. If not, the below-threshold
average can be used for background subtraction - The plot configuration depends on whether threshold and dark subtraction is used. Intensity projections
are also added to the plot, can be turned off (in the code). - In Interactive mode (see pyana_plotter), you can click on the image to
- change intensity range (color range): Left-click to set low limit, right-click to set high limit, middle-click to reset
- change threshold value and region of interest: Click on the rectangle, enter new values when prompted in terminal window
- switch to SlideShow mode when you are content with the display: Middle-click on the canvas and enter new display mode value.
- You can save the average image(s) or the selected single-shot images to file (numpy binary file)
To run this module by itself with pyana:

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 same as above, but 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. |
