9 // Utility Class for handling Raw data
10 // Does all transitions from Digits to Raw and vice versa,
11 // for simu and reconstruction
13 // Note: the current version is still simplified. Only
14 // one raw signal per digit is generated; either high-gain or low-gain
15 // Need to add concurrent high and low-gain info in the future
16 // No pedestal is added to the raw signal.
