Some Reminders

  • The low pT threshold for the jet reconstruction has to be lowered from 10 GeV/c (default in HI) to 1 GeV/c
  • Depending on statistics for each pT bin, it is very useful to optimize the pT, η and φ bin that will be used for the fitting this is done in fine_binning_ptRebin_noHF_noLowPt.config
  • Check that the cross section values for each of the bins is correct for pPb the can be found here
  • When checking the pT distribution in the "stitched" sample, make sure you make use of the weights t->Draw("jtpt","weight*(jtpt>0 && jtpt<400)")

Data Samples used

For this we need pp samples (most of the machinery is setup to intake the samples in HiForest format, but it can be modified for any root format). It is important to note that the samples should be without PileUp subtraction (i.e. ak3PF as opposed to akPU3PF)

Modules Used

Generating the DB files from the JEC txt files

  • Once the txt files for each algorithm are obtained the next step is to create the DB payloads. To do this it is necessary to use the config JetCorrectionDBWriter_cfg.py located in:
CondFormats/JetMETObjects/
  • Point the config to read the txt files under the data/ directory with the appropriate strings.

  • Once the DB file is produced check that the names of the payloads are correct by doing:
cmscond_list_iov -c sqlite_file:JEC_PA5TEV_CMSSW538_2013.db -a
  • Done!
