23 | 7 | Zhiwen Zhao | run160_0_all.csv (entries 990243) |
24 | |||
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 | 8 | Zhiwen Zhao | Cer11_1_pos: the peak sample number in the unit of 4ns of Cer11 quad1 |
33 | Cer11_5_pos: the peak sample number in the unit of 4ns of Cer11 sum |
||
34 | ec_ch: the channel with max peak height |
||
35 | sc_ch: the channel with max peak height |
||
36 | 7 | Zhiwen Zhao | |
37 | 8 | Zhiwen Zhao | Cer pos is relative to ec_pos, ec_pos and sc_pos are relative to trigger. |
