keyword=CT Spectrum Run 1813 (better format)Figure 1 shows the coincidence time spectrum using the DBB.t1 and DBB.t3 variables as 0.5*(DBB.t1[0]-DBB.t3[0]). One can and should use this combination to see the online CT peak. To remove the edtm pulser use "DBB.edtpr[0]==0" or alternatively "DBB.edtpl[0]==0". I also used the following cuts: abs(R.gold.dp)<0.045 abs(L.gold.dp)<0.01 DBB.evtypebits&(1<5) The coincidence shows up around +26 ns.
