raw - pedestals vs calibrow
Images before and after standard common mode correction
Detector/app/epix10ka_calib_components -t7 -S- raw data with subtracted pedestals.
...
Detector/app/epix10ka_calib_components -t9 --amin -2 --amax 2 -S # det.calib(evt, cmpars=(7,7,10,10))
Two plots abve show that common mode effect is seen and can be eliminated with standard algorithm for common mode correction. This algorithm does not work well in the central part of the detector where more than 50% of pixels have signal.
Segment 0-3 images with calibration rows
Raw data with subtracted pedestals for segments 0-3. Calibration rows show the difference between event calibrow and its average over 1000 events of the same run.

Scatter plots for segment 1 top and bottom half
Scatter plots show correlation between calibrow and segment row pixel intensities.
- epix10ka_calib_components -t103 -i1 --icrow 0 -S # left plot is a superposition of segment rows 0:176 vs calibrow 0
- epix10ka_calib_components -t103 -i1 --icrow 1 -S # right plot is a superposition of segment rows 176:352 vs calibrow 1
- No correlation observed
- Swapping of rows 0,1 between panel halves (to check possible mapping issue) does not work either.
Conclusion
- data sample shows common mode effect, which can be handled by standard cm correction, except overpopulated central region.
- in
Conclusion
- In raw - pedestal type of images calibration rows do not reproduce common behavior in ASIC's.
- quad 4 0 looks quite good - does not show significant difference between banks - hard to judge about calib-rows mapping.calibrows mapping, it might be wrong mapping yet.
- scatter plots do not show correlation
- Q: configuration parameters of calibrows - gain mode, what exactly do they show?
