   * 1) SUS-13-007: covers the single lepton + btag using the Lepton Spectrum (LS) and Delta Phi (DP) methods. Lepton studies are documented in AN-2013-035. Targeting Moriond.
   * 2) AOD rereco is used for periods A, B, and part C; prompt reco is used for part C and D.
   * 3) The triggers used for electrons: 
      * HLT_CleanPF(NoPU)HT300_Ele40_CaloIdVT_TrkIdT
      * HLT_Mu40_PF(NoPU)HT350
 and lepton + HT + MET 
      * HLT_PF(NoPU)HT350_Mu15_PFMET45
      * HLT_PF(NoPU)HT400_Mu5_PFMET45
      * HLT_CleanPF(NoPU)HT300_Ele15_CaloIdT_CaloIsoVL_TrkIdT_TrkIsoVL_PFMET45
      * HLT_CleanPF(NoPU)HT350_Ele5_CaloIdT_CaloIsoVL_TrkIdT_TrkIsoVL_PFMET45

Efficiencies are mesured via Z T&P in events that are acquired by the analysis triggers (therefore with correctly biased kinematics)

   * 4) Lepton selections are fully documented here: https://twiki.cern.ch/twiki/bin/view/CMS/SingleLepton2012#Electron_Selection https://twiki.cern.ch/twiki/bin/view/CMS/SingleLepton2012#Muon_Selection
   * 5) Lepton reconstruction and ID efficiency scale factors between data and MC (full simulation)
