Only listed segments are highlighted on plots:

Background

Background shape evaluated in exp=cxif5315:run=162

Background shape evaluated with common mode correction - central segments got offset to higher intensity

Image Added

Background shape evaluated without common mode correction - common mode offsets averaged out to zero and image represents true background shape.

Command to average data with options for processing algorithms:

det_ndarr_average -d exp=cxif5315:run=162 -s CxiDs2.0:Cspad.0 -n 10000 -m 5000 -a 3 -f nda-bkgd -p -v

skips 5000 and averages next 10000 events.
