SRD energy calibration for 2024A

SRD energy calibration for 2024A

created branch 164-srd-calibration-for-2024a to address this issue

To fix the global energy scale for the SRD measurement, I exploited the 3 calibration runs in which the 100 GeV muon beam impinged on each cell of this detector. Using this script, I evaluated the signal amplitude distribution and performed a fit with a Landau function convoluted with a Gaussian. The results are posted below. According to MC, the calibration constants are computed assuming that the mean energy deposition in the SRD is about 42 MeV.

Hi @pbisio ,

Looks good! What is the meaning of the blue curve? Red is "Landau (x) Gaussian", right?

The red curve is the convolution between a Landau and a Gaussian function, used for the fit. The blue one is the Landau resulting from this fitting procedure.

I printed this part of the model to verify that the MPV was correctly estimated.
