Introduction

This package contains the different HoughTransforms used in the HoughPatternTool and also the internal EDM. Every houghtransformer does both the histogram filling and the association step.

Class Overview

The MuonHoughPatternEvent package contains of following classes:

MuonHoughHisto2D: Histogram class, similar to Root's TH2D
MuonHoughHisto2DContainer: Container class of MuonHoughHisto2D
MuonHoughHit: Internal Hit class
MuonHoughHitContainer: Container class of MuonHoughHit
MuonHoughMathUtils: Class with Mathematical functions, both general and trackmodel specific
MuonHoughPattern: Internal Pattern class
MuonHoughPatternCollection: Container class of MuonHoughPattern
MuonHoughTransformSteering: class that steers the initialization of HoughTransformers
MuonHoughTransformer: abstract base class
MuonHoughTransformer_CurvedAtACylinder: HoughTransformer in rz plane with curved track model (Atlas magnets bend charged particles in rz plane). Assumes muons from interaction point
MuonHoughTransformer_rz: HoughTransformer in rz plance with straight track model, used for cosmics
MuonHoughTransformer_xy: HoughTransformer in xy plane with straight track model
MuonHoughTransformer_xyz: base class for HoughTransformers in carthesian coordinates, straight track model
MuonHoughTransformer_yz: HoughTransformer in yz plane with straight track model, currently not in use
