  1. Break down of Optimum Energy Alg. Derived from MC Truth v9 version: Tracker & LastLayer replaced by LikeliHood Param the same Profile less Tracker+LastLayer more As it was for DC2

  2. Profile & Parametric 24% All Methods 37% LkHd & Parametric 21% Parametric Only 18% Mistracked (McZDir > -.2): 8% (BAD)

  3. Cut at .3 DC2: 4 Methods / Resolution Model 2 s CTBBestEnergyRatio < 5

  4. Cut at .2 Direct Comparison Method BestEnergy2Ratio < 5

  5. Resolution Model sHi = .8 / sLow =1.5 Cut at .17 BestEnergyRatio < 5

  6. Resolution Model sHi = 1. / sLow =2. Cut at .2 BestEnergyRatio < 5

  7. Cut at .17 Direct Comparison Method 2: Only those reporting BestEnergyRatio < 5

  8. Energy resolutions when MC Truth is used to select Energy Method

  9. DC2 Pass 4 26153 Evts. BestEnergyProb > .35 26101 Evts. BestEnergyProb> .30 22343 Evts. CTBGAM > .5 22251 Evts. CTBGAM > .5

  10. Conclusions • DC2 and the new energy algs. Are essential equivalent • Opt. for using the new one mainly due to maintain-ability
