  3. CSV and fastPV Muon paths: /users/mait/FastPVandCSV/FastPVTest/V21 (Rate reduction (run:193336)) HLT_IsoMu17_eta2p1_CentralPFNoPUJet30_BTagCSV ~12% HLT_Mu17_eta2p1_CentralPFNoPUJet30_BTagICSV ~12% HLT_IsoMu17_eta2p1_CentralPFNoPUJet30_BTagIPIter HLT_Mu17_eta2p1_CentralPFNoPUJet30_BTagIPIter Electron paths: /users/mait/FastPVandCSV/FastPVandCSV/V3 ~9% HLT_Ele25_CaloIdVT_CaloIsoT_TrkIdT_TrkIsoT_CentralPFNoPUJet30_BTagCSV HLT_Ele25_CaloIdVT_CaloIsoT_TrkIdT_TrkIsoT_CentralPFNoPUJet30_BTagIPIter Sequences in *CSV paths: • lepton reconstruction • PFJetNoPu • L1FastJetCorrected • FastPrimaryVertex • BtagCSV (loose 0.245)

  4. CSV and fastPV efficiencies (running) /T_TuneZ2_t-channel_7TeV-powheg-tauola/Fall11-E7TeV_Ave32_50ns-v2/GEN-SIM-RAW-HLTDEBUG-RECO request ti transfer data to KIT t2? (now its in London Winsconsin - unstable)

  5. Rate reduction 5% & Prescales In the TSG coord meeting on Monday we made the request to evaluate the prescales of the control triggers of the column 5E33, which are responsible for about 18% of the total rate compared to about 12% for the 6E33 and 7E33 columns, to see if we can gain back 5% of the rate. And at the same time we asked to consider how to gain a further 5% from the main (unprescaled) paths. • HLT_IsoMu17_eta2p1_CentralPFNoPUJet30_BTagIPIter_v1 1.4Hz • HLT_IsoMu17_eta2p1_CentralPFNoPUJet30_v1 0.5Hz (Pre 20) • HLT_Mu17_eta2p1_CentralPFNoPUJet30_BTagIPIter_v1 0.5Hz (Pre 96) • HLT_Ele25_CaloIdVT_CaloIsoT_TrkIdT_TrkIsoT_CentralPFNoPUJet30_BTagIPIter_v6 6.0Hz • HLT_Ele25_CaloIdVT_CaloIsoT_TrkIdT_TrkIsoT_CentralPFNoPUJet30_v5 0.8Hz (Pre 125) some L1 seeds which are unprescaled at 5E33 will be prescaled (a52     L1_SingleEG20   262139  1)

  6. Online Beamspot https://hypernews.cern.ch/HyperNews/CMS/get/AUX/2012/05/13/21:53:43-8183-BeamSpotVariation_Sheet1.pdf run 193334/193336 • Variation wrt Online in % • HLT_IsoMu17_eta2p1_CentralPFNoPUJet30_BTagIPIter 0.86 • HLT_IsoMu17_eta2p1_CentralPFNoPUJet30 0.26 • HLT_Mu17_eta2p1_CentralPFNoPUJet30_BTagIPIter -1.29 • HLT_Ele25_CaloIdVT_CaloIsoT_TrkIdT_TrkIsoT_CentralPFNoPUJet30_BTagIPIter ‐0.55 • HLT_Ele25_CaloIdVT_CaloIsoT_TrkIdT_TrkIsoT_CentralPFNoPUJet30 -0.13 To check: 1) Increase of rates and possible impact on the CPU cost of the affected paths 2) Decrease of efficiency 3) set of "golden" event that groups should have provided to TSG to verify that the changes are not affecting them.
