Optics Calibration: TgY Calibration

Progress:

1.) Analyzed the rest of the Sieve-slit data.
2.) I will use these data to calibrate  TgTh and TgPh, using the SVD method.
3.) ...

dE/E Calibration

Progress:

1.) Finished the ADC calibration (will present results next week).
2.) Analyzed approx. 200 runs on farm.
3.) I will use this runs to plot high-energy deuterons at lower paddles more clearly
----------------------------
4.)  Started with the TDC calibration
5.) Looked in the code, to learn how things work.
6.) Came accross problems. Please see plots below:
