0004 # ------------------
0005 #
0006 # This configuration demonstrates how to run the L2L3 correction producers
0007 # for kT R=0.4 CaloJets and PFJets.
0008 #
0009 # Note that you can switch between different sets of corrections
0010 # (e.g. Summer09 and Summer09_7TeV) by simply setting the below 'era'
0011 # parameter accordingly!
0012 #
0013 # The services and producers necessary to provide L2 & L3 corrections for
0014 # kT R=0.4 jets are cloned from the already existing versions for
0015 # AntiKt R=0.5. Any other available algorithms (e.g. SISCone) can be
0016 # configured accordingly.
0017 #
0018 # The job creates 'histos.root' which contains the jet pT spectra for
0019 # calorimeter and pflow jets before and after the application of the
0020 # L2 (relative) and L3 (absolute) corrections.
