Which plots are in the Top Muon HLT DQM?


14 Efficiency related plots:
     D0, Z0, Charge, eta, phi, pt, pt_max
     7 distributions * 2 histos/distrib = 14 plots
6   Fake related plots: pt, eta, phi (ONLY produced for HLT Triggers)
1 Charge Flip
2 isolation
4 Beamspot track parameters: D0, Z0 eff from beamspot
2 Phi Vs Eta
3 Resolution: Pt, eta phi

Examples of plots

A talk demonstrating some of the plots is available on indico: http://indico.cern.ch/conferenceDisplay.py?confId=68436

A pdf with just the plots and no explaination is available here: https://twiki.cern.ch/twiki/pub/CMSPublic/SWGuideMuonHLTTopPAGDQM/ttbar_3_1_0_pre9.pdf

What selections are used on the muons that go into these plots?

The selections are available in the CMSSW CVS. There are two configuration: COSMICS and COLLISIONS.

Specifically, the selection for CRAFT09 cosmic data is:

collectionName = cms.untracked.string ("TopCosmicConfig3"),
trackCollection = cms.untracked.string ("outerTrack"),
requiredTriggers = cms.untracked.vstring(""),
d0cut = cms.untracked.double(1000.0), # any where
z0cut = cms.untracked.double(1000.0), # any where
recoCuts = cms.untracked.string ("abs(eta) < 2.0"),
hltCuts  = cms.untracked.string ("abs(eta) < 2.0")

In other words, we select stand-alone muons with |eta| < 2.0, and any d0 or z0, and match them to hlt muons with |eta| < 2.0.

[b]Currrently, we also require >= 2 jets.[/b]

The purpose of this selection is to put events in the histogram to make sure that we can see events going through the whole workflow. These events won't be top-like.

Where is the source code?

If you check out the latest SWGuideMuonHLTOfflineDQM, it includes the latest Top DQM module.
