Data analysis

file location /work/solid/cc_pro

run160_0_all.csv
run 160: scaler run, 30uA on PolHe3 target, fadc mode 1 single every 4ns, large angle, CO2
it has event by event info and the entries are
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
........................................................................
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.
ec_pos: the peak sample number in the unit of 4ns
ec_nhits: number of hits
ec_sum: sum of all channels of peak height
sc_* : similar things for SC2 which is the plane behind Cerenkov tube
Cer11_1_peak: peak height of Cer11 quad1
Cer11_5_peak: peak height of Cer11 sum
ec_ch: the channel channel with max peak height
sc_ch: the channel channel with max peak height

cer_pos is relative to ec_pos, ec_pos and sc_pos are relative to trigger.
