25 | 1 | Zhiwen Zhao | ec_peak: the peak height of the channel with max peak height, but about 90% of the events have only one channel fired, so it is close to the sum. |
26 | ec_pos: the peak sample number in the unit of 4ns |
||
27 | ec_nhits: number of hits |
||
28 | ec_sum: sum of all channels of peak height |
||
29 | sc_* : similar things for SC2 which is the plane behind Cerenkov tube |
||
30 | Cer11_1_peak: peak height of Cer11 quad1 |
||
31 | Cer11_5_peak: peak height of Cer11 sum |
||
32 | ec_ch: the channel channel with max peak height |
||
33 | sc_ch: the channel channel with max peak height |
