keyword=TDC cerenkov with t2 cut
Looking at the TDC for run# 1088. Applying a t2 cut (cut2 = Form("(Ndata.DL.edtpbb==0)&&((abs(DL.t2-650)<10))");) produces the red histo. Applying (cut1 = Form("(Ndata.DL.edtpbb==0)&&((abs(DL.t2-650)>10))"); gives the blue histo. The green is only with the electronic deadtime pulse cut. It is peculiar that cut1 yields a sharper peak here.
