Once all the signals quantities are stored in n-tuples, the class `/$HOME/foot_turin/Script/PythonScript/sw_standalone/read_ntuple.py` allows to quickly generate all the histograms/plots required by the user.
The function in `$HOME/foot_turin/Script/PythonScript/sw_standalone/energy_resolution.py` performs the energy resolution evaluation from the Amplitude and Charge histograms created in step 3. It is called by the `Jupyter Notebook` script in `$HOME/foot_turin/Script/PythonScript/sw_standalone/notebook/FitCalorimeterDistribution.ipynb`
