23 | // for simu and reconstruction | |
24 | // | |
25 | // Note: the current version is still simplified. Only | |
26 | // one raw signal per digit is generated; either high-gain or low-gain | |
27 | // Need to add concurrent high and low-gain info in the future | |
28 | // No pedestal is added to the raw signal. | |
