3.9. G4Sipm digi

A G4SipmDigi is created by the G4SipmDigitizer. It stores the following properties:

• G4Sipm id
• G4SipmCellId
• The time of the breakdown
• The weight, i.e. the gain of the cell at the breakdown whereas one equals to 1 p.e.
• G4SipmDigiType, can be either UNDEFINED, THERMAL, PHOTON, CROSSTALK or AFTERPULSE

Please also refer to the Geant4 digitization documentation.

3.9.1. G4Sipm digi collection

Each G4SipmDigiCollection is uniquely identified by the G4SipmId. Thus, given the id is zero:

g4sipmDigis-0
