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
files = exp=amo74213:run=93:xtc

The file with accumulated hit pixels can be obtained using configuration file:
