[d2n-analysis-talk] H2 coin elastic BB cer

[posik at jlab.org]

Hi all,

   In our last meeting Brad had suggested that I look at the H2 elastic
events in the Cerenkov with out mirror cuts applied. So I made a plot
of the BB cer ADCs that satisfy the proton cut (good coin (T5 trigger)
events that show up in the LHRS with BB one track cut and BB target
cut(abs(BB.tr.vz)<0.2), this is seen in the plot adc_proton.gif. I then
plotted the same ADCs, but with the proton cut + a BB cer TDC cut. This
can be seen in the plot adc_proton_tdc_ct.gif.

  I also double checked the construction of the T5, our coin trigger, and
it is a T1 (low threshold BB shower trigger) && a T3 (LHRS trigger)
