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.
- Comparison of spectra of pixels from central region and side bands shows that resolution is significantly better in central region.
- The gain correction is small comparing to the amplitude spread due to resolution, especially for side bands.
- In run 900 (with a large transmission = 0.02, nu=2) the 0-,1-,2-photon peaks are not resolved even for central band both WITH and WITHOUT gain correction.
