36 | |||
37 | 9 | Zhiwen Zhao | id: event id |
38 | 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. |
39 | ec_pos: the peak sample number in the unit of 4ns |
||
40 | ec_nhits: number of hits |
||
41 | ec_sum: sum of all channels of peak height |
||
42 | sc_* : similar things for SC2 which is the plane behind Cerenkov tube |
||
43 | Cer11_1_peak: peak height of Cer11 quad1 |
||
44 | Cer11_5_peak: peak height of Cer11 sum |
||
45 | 8 | Zhiwen Zhao | Cer11_1_pos: the peak sample number in the unit of 4ns of Cer11 quad1 |
46 | Cer11_5_pos: the peak sample number in the unit of 4ns of Cer11 sum |
||
47 | ec_ch: the channel with max peak height |
||
48 | sc_ch: the channel with max peak height |
||
49 | 7 | Zhiwen Zhao | |
50 | 8 | Zhiwen Zhao | Cer pos is relative to ec_pos, ec_pos and sc_pos are relative to trigger. |
