12 MIP gains ver1.0 (all tiles, also BTOW)

 This is still work in progress, same algo as on previous post.

Now I run on  12M events (was 6 M) and do rudimentary QA on MIP spectra, which results with ~10% channel loss (the bottom figure). However, the average MIP response per tile is close to the final value.

Conclusion: only green & light yellow tiles have reasonable MIP response of ~15 ADC. For blue we need to rise HV, for red we can lower it (to reduce after pulsing). White area are masked/dead pixels.

Fig 1: BPRS MIP gains= gauss fit to MIP peak.

A) gains vs. eta & phi to see BPM pattern. B) gains with errors vs. softID, C) sigma MIP shape, D) tiles killed in QA

Fig 2: BTOW MIP gains= gauss fit to MIP peak. Content of this plot may change in next iteration.

A) gains vs. eta & phi. "ideal" MIP is at ADC=18, all towers. Yellow& red have significantly to high HV, light blue & blue have too low HV.

B) gains with errors vs. softID, C) sigma MIP shape, D) towers killed in QA
