Run the bash script titled 'jeff', which takes the run number as an argument. This script will automatically convert the .dat file to a .root file and then open it in root. The script: File:Jeff.txt.
bash jeff 4716
The first index of evt.TDC1190 is the hit #. The second index increases consecutively with TDC channel number, but the index starts from 1, while the TDC channels start at 0. Common ROOT plot commands for copy-past: First hit minus second hit:
R1DC->Draw("(evt.TDC1190[2][1]-evt.TDC1190[1][1])")
PMT difference:
R1DC->Draw("(evt.TDC1190[1][2]-evt.TDC1190[1][3])/10>>h(n,min,max)",(Long64_t)6394][2]!=0&&evt.TDC1190[1][3]!=0")
PMT Sum, where evt.TDC1190[1][1] is the trigger:
R1DC->Draw("(evt.TDC1190[1][2]+evt.TDC1190[1][3]-2*evt.TDC1190[1][1])/10>>h(1000,-500,500)","evt.TDC1190[1][2]!=0&&evt.TDC1190[1][3]!=0")
TDC Calibration
A linear fit was done by using a set delay of 500,600,700, and 800 ns.
