Example for module ImgAlgos::ImgHitFinder
See Module ImgAlgos::ImgHitFinder
ImgHitFinder in regular mode needs in file with pedestals (offset) to correct the image and file with threshold.
In amo74213 run 93 these files can be obtained directly from data, discarding signal hits as outliers using
ImgAlgos.ImgAverage module as follows with configuration file:
| Code Block |

# File: psana-amo74213-r0093-opal-img-average.cfg
[psana]
#files = /reg/d/psdm/AMO/amo74213/xtc/e269-r0093-s05-c00.xtc

Run psana using command:
| Code Block |
|---|
psana -c psana-amo74213-r0093-opal-img-average.cfg
|
At the end of this procedure two files will be created:
- img-ave-for-peds-r0093.dat - may be used for pedestal subtraction:
- img-rms-for-thre-r0093.dat - may be used multiplied by number of rms as a threshold:
The file with accumulated hit pixels can be obtained using configuration file:

and run it by the command:
| Code Block |
|---|
psana -c psana-amo74213-r0093-opal-img-hit-finder.cfg

Which creates the file: img-sum-result-r0093.dat (thre_mode = 3):
img-sum-result-r0093.dat (thre_mode = 2):
