    keyword=Shower threshold vs Shower X

    Fig1. Total energy in shower for the electrons vs shower x (dispersive direction).

    Fig2. Trigger threshold ( the little bump on the low x is due to events missing re-timing..it should go away now after we removed the delay on T2 that we added earlier)

    The threshold is around 650-700MeV. If we reduce it further then we have to prescale T2 inorder to keep the deadtime low.
