Global tags for 2015 onwards

Now need to use DB2 and get tag info from DAS, example

ECALELFS site, reReco tags

Official GT for September 2016 re-Reco:
80X_dataRun2_2016SeptRepro_v3
Used in Cal_Oct2016_IC_piZero_v1.py

In DAS put:

config dataset=/DoubleMuon/Run2016G-PromptReco-v1/AOD

returns:
Config: cmsRun
Creation time: 2016-08-12 12:59:53, Global Tag: 80X_dataRun2_Prompt_v10, Pset hash: GIBBERISH, Release: CMSSW_8_0_17

In python file put:

process.load("Configuration.StandardSequences.FrontierConditions_GlobalTag_condDBv2_cff")
# New Tag format for 2015, also ::All no longer required 
Tag = '74X_dataRun2_Prompt_v1'

Notes on 2011 global tags

Example datsets from Paolo Rumerio, 20 Feb 2012
/SingleElectron/Run2011A-May10ReReco-v1/AOD 160329163869 Re-reco of initial data with 42
/ElectronHad/Run2011A-PromptReco-v4/AOD 165071168437 Prompt reco to ~1fb_1, for EPS ?
/ElectronHad/Run2011A-05Aug2011-v1/AOD 170053172619 Re-reco fixing a laser bug for ICHEP, values going abssurd,
  1 PN bad in May so fit went nuts across 400 channels
/ElectronHad/Run2011A-PromptReco-v6/AOD 172620175770 Prompt reco for the rest of 2011A, to end Aug, from ~5th Aug, 2-3 weeks only
/ElectronHad/Run2011B-PromptReco-v1/AOD 175832180296 All of 2011B, Sep/Oct

With 44

  • re-reco of everything, all datasets, for all runs in Nov 2011
  • Has data driven corrections during Sep, since no jumps.
  • Rest of Oct and early Sep is fit, wanted for 8th Nov (was a waste of time, nobody used it)
  • Weren't ready to do entire 2011B with data driven approach.
  • At start of Sep 2011, could use fit, since no jumps

Full year, fully data driven, Nov 30th re-reco for Higgs data only

  • with FT_R_42_V21B.
