60CDF are not ready and differences didn't measured yet.
61
62- 48 channel for amplitude: very preliminary, QTC features are not
63known now, preliminary i put as T1 time signal for this PMT in first
64channel and T1+A in second, where A=Log(Amplitude);
65and the same for amplified but A=Log(10*Amplitude).
66
67- T0-A and T0-C 2 channels
68- T0A-T0C vertex information
69- Time Meaner where T0C TOF increase to the T0A TOF distance
70- 6 multiplicity signals the same way as amplitude and with the same
