Introduction
• R45 = (T4 – T5)/(T4 + T5) • T4 and T5 are in GeV.• Results for both channel and RBX wise are
reported.• Number of the vertices is used as the PU
measure.• GoodPrimaryVertexFilter and HBHENoiseFilter
are applied. process.HBHENoiseFilter.useTS4TS5 = cms.bool(False)10/7/2011

Efficiency of Noise Filter• The variable useTS4TS5 is turned on/off.• The efficiencygoes down by increasing the number of theVertices.
The plot will be updated with y-label.
Points are fitted with a
horizontal line
