Gain correction factor distribution over quad-2 pixels in different runs
Amplitude spectra with (and without) corrected gain
Run 901, trans.=0.002
- Spectrum is shown for events 1,11,21,31, and 41, respectively.
- The gain correction factor is set to "0" for bad pixels . This explains the one-bin peak at "0" amplitude.are discarded from these spectra.

Run 902, trans.=0.005
- Spectrum is shown for events 1,11,21,31, and 41, respectively.
- The gain correction factor is set to "0" for bad pixels . This explains the one-bin peak at "0" amplitude.are discarded from these spectra.

Run 900, trans.=0.02
- Spectrum is shown for events 1,11,21,31, and 41, respectively.
- Fit is not applied because peaks are not distinguished
...
Run 900, trans.=0.02 WITHOUT GAIN CORRECTION:
Conclusion
- Gain factors have the RMS spread ~5-10% depending on high/low-gain mode and intensity of illumination
- There is no significant improvements of the amplitude spectrum after the gain correction is applied
