For data processing of exp=cxif5315:run=169 two masks were produced for arc and equatorial regions:
Peak finder
Who is doing what
Peak finding algorithm is based on psana module ImgAlgos::NDArrDropletFinder with preceded CSPAD ndarray producer CSPadPixCoords::CSPadNDArrProducer and its calibration Algos::NDArrCalib. Detector geometry information is provided by the moduleImgAlgos::PixCoordsProducer. Configuration file psana-cxif5315-r0169-cspad-ds2-NDArrDropletFinder.cfg (download) defines parameters for these modules. Two instances of modules are used in order to process two region of interests for arc and equator.
For each event all psana modules are executed first and save the list of found peaks in the event store. Then, python script psana-cxif5315-r0169-cspad-ds2-NDArrDropletFinder.py (download) works with lists of peaks, performs additional selection, plots image with peaks, and saves selected peaks in the file.
Latest version of packages
A few minor code changes have been made during work on this project. Until the next release is available, latest version of packages need to be compiled on the top of release ana-0.14.1 in the local release directory
| Code Block |
|---|
Pkg/Rel TEST BASE(ana-0.14.1)
TBA |
External files
Configuration script expects a few files in the local directory work/; two files with masks and file with a shape of background.
In the local or standard calib/ directory the files for calibration should be available for geometry, pedestals, pixel_status, common_mode etc., whatever is giing to be used in the modules.
How to run
Use command:
| Code Block |
|---|
python psana-cxif5315-r0169-cspad-ds2-NDArrDropletFinder.py |
Example
Image with peaks for separate and both regions can be plotted:
File with table of parameters for found peaks has an unique name like work/peaks-2015-04-14-15:57:44-cxif5315-r0169.txt and contains records with peak parameters:
