ang brings us an image: - the same image, but spectrum is shown in the range (-100, 100) ADU. There is no peak at -35ADUThis event looks good.

Event #36: Image Addedlooks like left-side sensor is not corrected for common mode fluctuation...

In stead of default common_mode parameters (1,25,25,100) let us try (1,50,10,100) in the file

/reg/d/psdm/CXI/cxi86415/calib/CsPad2x2::CalibV1/CxiDg3.0:Cspad2x2.0/common_mode/9-end.data

The same image looks better now: Image Added

Recommendation: try to play with common mode parameters.
