Examples for exp=cxif5315:run=165

Example 1

Shows how to get ndarray with CSPAD  data in psana, calibrate it, find peaks (droplets) in imaging data and plot them offline.

Configuration file: psana-cxif5315-r0165-cspad-ds2-NDArrDropletFinder.cfg

...

Example 2

Shows how to get ndarray with CSPAD  data in psana, calibrate it, prepare and apply mask, find peaks (droplets) in imaging data and plot them offline.

Configuration file: psana-cxif5315-r0165-cspad-ds2-Configuration file: psana-cxif5315-r0165-cspad-ds2-NDArrDropletFinder-v2.cfg

Example 3

Example 3 has the same functionality as Example 2. Also it shows how to access psana data structures from the python script, reconstruct CSPAD image and interactively plot it with overlayed peaks.

file with mask: roi_mask_nda_v3.txt

psana configuration file psana-cxif5315-r0165-cspad-ds2-NDArrDropletFinder-v3.cfg

python script for interactive psana: psana-cxif5315-r0165-cspad-ds2-NDArrDropletFinder-v3.py

Interactive job can be launched by the command:

./psana-cxif5315-r0165-cspad-ds2-NDArrDropletFinder-v3.py

which does all work and plots images with peaks like Image Added
