It was found in in the Hcal Dijet Logbook page 1 ( Sec.4.2.1 ) from the ET_peak / Pthat_threshold for tag jets in 2009 sample (PThat > 30) that the the uncorrected tag jet energy is underestimated by factor ~2. And the "unbiased" HF correction was found to be 0.50 (Sec.5.5). => It looks like the jet energy scale in HF is roughly correct.

Puprose of this study: try to see here the jet scale recovery for probe jets as going from barrel region to HF, by looking at the evolution of the ET(probe jet) distribution.

Input sample: 2009 PThat>30, 10 TeV Version 1, one root file QCD_Pt30_10TeV.hi_100.root with 70946 evs

Plots made interactively with the script .
