ptLUTs generation

Introduction

The purpose of the CSC Track-Finder is to link trigger primitives (track segments) from individual CSC stations into complete tracks, measure the transverse momentum pT from the sagitta induced by the magnetic bending, and report the number and quality of tracks to the Level-1 Global Muon Trigger. This objective is complicated by the non-uniform magnetic field in the CMS endcap and by the high background rates; consequently, the present design incorporates full three-dimensional information into the track-finding and measurement procedures.

05.03.2010	Anna committed code L1Trigger/CSCTrackFinder/ in the CVS with tag-name: V00-18-00. The new PtLUTs L1CSCPtLUT_4N9.bin.gz are generated by default in this version (method 4).	Anna asked Vasile Mihai Ghete to put it in the next release of CMSSW. We are waiting for the reply now.
04.03.2010	Gian Piero and Anna uploaded new PtLUTs L1CSCPtLUT_4N9.bin.gz at Point 5	This information is posted at Trigger elog ID 183962 and CSC elog ID 183926
