Find a parameterization for LYSO waveform (2025e run)
For illustration, the typical shape of LYSO signals is (12813-1-100)
From run 12814, LYSO was connected to a pole-zero suppression circuit. The signal shape changed (12814-1-200)
Note, in particular, the negative tail after the main pulse, resulting from the capacitance inside the pole-zero suppression circuit.
A proper parameterization for both cases is necessary to run waveform fitting.
