1 October 31, 2008METDQM Study1 Summary from MET DQM Plot Scanning

2 October 31, 2008METDQM Study2 MET DQM Plots https://cmsweb.cern.ch/dqm/tier-0/ From CRAFT data JetMET POG DQM is already routinely run

3 October 31, 2008METDQM Study3 Run 66594 MEx (GeV) MEy (GeV) METPhi (rad) Lumi Section With HF Barrel+Endcap Only First few lumi sections appear to be problematic. Number of events

4 October 31, 2008METDQM Study4 Run 66594 cont’d  Zoom-in view  Problem only in a first few lumi sections  On a lumi section based method, can keep the majority of events

5 October 31, 2008METDQM Study5 Run 66594 cont’d  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

6 October 31, 2008METDQM Study6 Run 66714 MEx (GeV) MEy (GeV) METPhi (rad) Lumi Section With HF Barrel+Endcap Only No major problem. Number of events

7 October 31, 2008METDQM Study7 Run 66714 cont’d  Data certification output Good run

8 October 31, 2008METDQM Study8 Run 66746 MEx (GeV) MEy (GeV) METPhi (rad) Lumi Section With HF Barrel+Endcap Only Noise in HF at phi~0.8 Check of the mean MEx or MEy will detecot this problem. Number of events

9 October 31, 2008METDQM Study9 Run 66746 cont’d  Data certification output MET without HF mostly OK

10 October 31, 2008METDQM Study10 Run 67124 MEx (GeV) MEy (GeV) METPhi (rad) Lumi Section With HF Barrel+Endcap Only Number of events met with/withtou HF seem to suffer from hot tower(s)

11 October 31, 2008METDQM Study11 Run 67124 cont’d  Data certification outputs Bad Run

12 October 31, 2008METDQM Study12 Run 68021 MEx (GeV) MEy (GeV) METPhi (rad) Lumi Section With HF Barrel+Endcap Only Number of events No major problem.

13 October 31, 2008METDQM Study13 Run 68021 cont’d  Data certification outputs
