Gain Correction Factors
Run 901, 902, and low gain 903, 904, 905, and 906
with transmission 0.002, 0.005, 0.005, 0.1, 0.5, 1, respectively
Gain correction factor distribution over quad pixels in different runs
Amplitude spectra with 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.
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.
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
