14 | 4 | Zhiwen Zhao | run 160: production run, 30uA on PolHe3 target, fadc mode 1 single every 4ns, large angle, CO2 |
15 | |||
16 | run160_0_all.zip and run160_0_all.csv has event by event info and the entries are |
||
17 | 1 | Zhiwen Zhao | ec_peak,ec_pos,ec_nhits,ec_sum,sc_peak,sc_pos,sc_nhits,sc_sum,Cer11_1_peak,Cer11_2_peak,Cer11_3_peak,Cer11_4_peak,Cer11_5_peak,......,ec_ch,sc_ch |
18 | ........................................................................ |
||
19 | 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. |
||
20 | ec_pos: the peak sample number in the unit of 4ns |
||
21 | ec_nhits: number of hits |
||
22 | ec_sum: sum of all channels of peak height |
||
23 | sc_* : similar things for SC2 which is the plane behind Cerenkov tube |
||
24 | Cer11_1_peak: peak height of Cer11 quad1 |
||
25 | Cer11_5_peak: peak height of Cer11 sum |
||
26 | ec_ch: the channel channel with max peak height |
||
27 | sc_ch: the channel channel with max peak height |
||
28 | 2 | Zhiwen Zhao | |
29 | cer_pos is relative to ec_pos, ec_pos and sc_pos are relative to trigger. |
