  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/JetExample#Tracks_Jet
• back to https://twiki.cern.ch/twiki/bin/view/CMS/JetExample
• back to https://twiki.cern.ch/twiki/bin/view/CMS/JetMET
  • reads through the subgroup names
  • goes top
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/JetMET#Sub_group_Twiki_Pages
  • decides to see some other page

• goes to analysis guideline (in a tab)
• goes back to workbook https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook
  • sees data formats and data
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookDataFormats
  • says that this gives the essential introduction to the terms
  • scroll down
  • thinks of going to qcd, to jet and to what jet parameter are available to look at
• back to workbook https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookIntroAnalTools
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookParticleCandidates
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookParticleCandidates#WhereAreCands
  • thinks of getting some information here
  • find jet contituents but no link
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/AOD
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/SWGuideAodDataTable
  • scrolls down, finds jet collections
• clicks on the collection link and comes to http://cms-service-sdtweb.web.cern.ch/cms-service-sdtweb/doxygen/CMSSW_1_6_12/doc/html/d4/ddc/classreco_1_1CaloJet.html

Question 3: Where would you look for an example on how to access jet data and basic analysis example?

• finds the jet analysis link in the left bar
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookJetAnalysis
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook210JetAnalysis
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook210JetAnalysis#RunJet
  • will look for an example code
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook210JetAnalysis#SetEnv
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook210JetAnalysis#JetAna
  • thinks this will give some idea, but sees that this just for running root
  • says that will look at one of the data samples
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook210JetAnalysis#RecoExamples
  • clicks on (not found)
  • says that this would be the place where to look for information
