3. Producing the plots Started from the Top WG Twiki - https://twiki.cern.ch/twiki/bin/view/AtlasProtected/TopWorkingGroup https://twiki.cern.ch/twiki/bin/view/AtlasProtected/TopWorkingGroup - TopPhysdAODValidation version 15.6.10.4 - hn-atlas-top-reconstruction@cern.ch (info on D2PD production) - hn-atlas-csc-toptrigger@cern.ch (trigger forum) hn-atlas-csc-toptrigger@cern.ch List of Top dAODs from 2010 Collisions - group.phys- top.D2PD_rel15.6.11.3.1_data10_7TeV.00160387.physics_Egamma.merge.AOD.f280_m568.20100 804_00_D2AODM_TOPEL Data is broke up into different trigger streams - egamma - Muon - JetTauEtMiss - minBias 3

5. Trigger L1 Hardware trigger Information is taken from Calorimeter and Muon Spectrometer L1_EM10, L1_EM14, L1XE40 and L1_MU10 all pass events L2 Software Trigger Looks at RoI L2_e10_medium, L2_e15_medium and L2_e20_loose all pass events. EF Offline reconstruction Algs are used Only partial reconstruction takes place at RoI EF_e10_medium, EF_e15_medium and EF_e20_loose NO Prescale - 1 to 1 events passed 5
