Event 8 (counting from 0) for all plots.

Calibration

Use original calib directory /reg/d/psdm/XPP/xppn4116/calib

Raw data

ave=3804.986 rms=186.705

Data - pedestals

ave=-9.398 rms=8.544

Apply versions of common mode parameters

Default

nda_cdata = det.calib(evt) # default cmpars=(4, 7, 30, 10)

cmpars=(4, 7, 30, 30)

nda_cdata = det.calib(evt, cmpars=(4, 7, 30, 30))

ave=0.786 rms=8.064

cmpars=(4, 6, 30, 30)

nda_cdata = det.calib(evt, cmpars=(4, 6, 30, 30))

ave=0.786 rms=8.064

Conclusion

• default parameters do not work well in this experiment because larger correction is required.
• the is no difference in results between cmpars=(4, 6, 30, 30) and (4, 7, 30, 30).
