Plots for "Performance study of the level-1 di-muon trigger" CSC book chapter

Introduction

This page contains all plots in the CSC note "Production Cross-Section Measurements and Study of the Properties of the Exclusive B+→J/Ψ K+ Channel" which forms a chapter of the CSC book "Expected Performance of the ATLAS Experiment Detector, Trigger, Physics", CERN-OPEN-2008-020, arXiv:0901.0512.
