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.
