3. Cont’d ~2500 (13.3%) events in Pt=10.0 - 10.5 GeV/c of the endplug PF jet Pt plots from 392. Considering this, 7.8% jet yield reduction in the endplug corresponds to about 2-3% jet pt reduction in 394. We are expecting ~10% energy reduction in HE, and the PF Neutral Hadron Fraction changes from 10% to 40% in ranges of |eta| from 1.3 to 3.0 (PFT-10-002, Fig 11). The observation appears consistent with the expectation.
