  1. Summary from MET DQM Plot Scanning METDQM Study

  2. MET DQM Plots From CRAFT data https://cmsweb.cern.ch/dqm/tier-0/ JetMET POG DQM is already routinely run METDQM Study

  3. Run 66594 With HF Lumi Section Number of events Barrel+Endcap Only Lumi Section Number of events METPhi (rad) MEx (GeV) MEy (GeV) First few lumi sections appear to be problematic. METDQM Study

  4. Zoom-in view Problem only in a first few lumi sections On a lumi section based method, can keep the majority of events Run 66594 cont’d METDQM Study

  5. Data certification Looking at Chi2 of double Gaussian fits: reduced chi2 <20 (lum section) or 200 (entire run) (Need to adjust the criteria based on the statistics) Mean of the fitted Gaussian form: within +-10 GeV Run 66594 cont’d METDQM Study

  6. Run 66714 With HF Lumi Section Number of events Barrel+Endcap Only Lumi Section Number of events MEy (GeV) METPhi (rad) MEx (GeV) No major problem. METDQM Study

  7. Run 66714 cont’d • Data certification output Good run METDQM Study

  8. Run 66746 With HF Lumi Section Noise in HF at phi~0.8 Number of events Barrel+Endcap Only Lumi Section Number of events METPhi (rad) MEx (GeV) MEy (GeV) Check of the mean MEx or MEy will detecot this problem. METDQM Study

  9. Run 66746 cont’d • Data certification output MET without HF mostly OK METDQM Study

  10. Run 67124 With HF Lumi Section Number of events Barrel+Endcap Only Lumi Section Number of events METPhi (rad) MEx (GeV) MEy (GeV) met with/withtou HF seem to suffer from hot tower(s) METDQM Study

  11. Run 67124 cont’d • Data certification outputs Bad Run METDQM Study

  12. Run 68021 With HF Lumi Section Number of events Barrel+Endcap Only Lumi Section Number of events METPhi (rad) MEx (GeV) MEy (GeV) No major problem. METDQM Study

  13. Run 68021 cont’d • Data certification outputs METDQM Study
