Cut | Purpose | Gamma Effic | Bkg Effic | Expression |
|---|---|---|---|---|
BasicTileCut | Reject events with track pointing at struck tile: | 95.1% | 8.1% | Tkr1SSDVeto == 0 && AcdTkr1ActiveDist > -16 && AcdTkr1ActDistTileEnergy > .4 |
RibbonCut | Reject events with track pointing at struck ribbon | 94.9% | 7.7% | (AcdRibbonActDist > -(2 +350/sqrt(max(20,CTBBestEnergy))) && Tkr1SSDVeto < 3 && AcdRibbonEnergy > .05 ) |
TotalTileEnergyCut | Reject events with excess ACD total energy | 89.3% | 1.2% | AcdTotalTileEventEnergyRatio > .8 or (AcdTkr1ActiveDistENorm > -300 && AcdTotalTileEventEnergyRatio > max(.005, .1 - .0001*AcdTkr1ActiveDistENorm)) |
CornerCut | Reject event in the corner gap of the ACD | 88.3% | 1.1% | ((Tkr1LATEdge/1.5) ^ 2 + (AcdCornerDocaENorm - 10)^ 2 < 3800 or (Tkr1LATEdge < 80 && abs(AcdCornerDocaENorm-2) < 4)) && Tkr1SSDVeto < 3 |
TileEdgeCut: | Reject events at tile edges with decreased signal | 88.1% | 1.1% | abs(AcdTkr1ActiveDistENorm) < 15 && AcdTotalTileEventEnergyRatio > .005 |
