CMS list of validated runs for p-p 2011 data taking, reference data for heavy-ion data analysis, only valid muons

CMS list of validated runs Cert_160404-180252_7TeV_PromptReco_Collisions11_JSON_MuonPhys.txt, CMS Collaboration

Environment Validation Heavy-ion physics CMS CERN-LHC


Description

This file describes which luminosity sections in which runs are considered good and should be processed when used as reference data for heavy-ion data analysis, for analyses requiring only valid muons.

This list covers 2011 p-p data taking at 7 TeV, between run numbers 160404 and 180252.

Characteristics

1 files. 13.9 KiB in total.

How was the validation done?

During data taking all the runs recorded by CMS are certified as good for physics analysis if all subdetectors, trigger, lumi and physics objects (tracking, electron, muon, photon, jet and MET) show the expected performance. Certification is based first on the offline shifters evaluation and later on the feedback provided by detector and Physics Object Group experts. Based on the above information, which is stored in a specific database called Run Registry, the Data Quality Monitoring group verifies the consistency of the certification and prepares a json file of certified runs to be used for physics analysis. For each reprocessing of the raw data, the above mentioned steps are repeated. For more information see:

How to use?

Add the following lines in the configuration file for a cmsRun job:

   import FWCore.ParameterSet.Config as cms
   import FWCore.PythonUtilities.LumiList as LumiList
   goodJSON = 'Cert_160404-180252_7TeV_PromptReco_Collisions11_JSON_MuonPhys.txt'
   myLumis = LumiList.LumiList(filename = goodJSON).getCMSSWString().split(',') 

Add the file path if needed in the file name.

Add the following statements after the process.source input file definition:

   process.source.lumisToProcess = cms.untracked.VLuminosityBlockRange()
   process.source.lumisToProcess.extend(myLumis)

Note that the two last statements must be placed after the process.source statement defining the input files.
