22 | // Utility Class for handling Raw data | |
23 | // Does all transitions from Digits to Raw and vice versa, | |
24 | // for simu and reconstruction | |
25 | // | |
26 | // Note: the current version is still simplified. Only | |
27 | // one raw signal per digit is generated; either high-gain or low-gain | |
28 | // Need to add concurrent high and low-gain info in the future | |
29 | // No pedestal is added to the raw signal. | |
