Overview

This package provides a tool, MuonClusterOnTrackTool, which turns Muon::MuonCluster into Muon::MuonClusterOnTrack objects using a given trajectory prediction. The Muon::MuonCluster class groups measurements originating from the following detector technologies:

• CSC - Cathode Strip Chambers, in the far endcap
• RPC - Resistive Plate Chambers, in the barrel
• TGC - Thin Gap Chambers, in the endcap

In the current version of this tool, no corrections are actually performed for RPC or TGC, but the information is only copied into the corresponding Trk::RIO_OnTrack objects. An individual error scaling can be applied at this point separately for each of the three technologies. The error scaling is controlled centrally by jobOptions in the Trk::RIO_OnTrackCreator package. It is, of course, switched off by default.

More general information on RIO_OnTrackCreation and instructions how to use these tools can be found under Trk::RIO_OnTrackCreator.

CSC clusters

The position resolution for CSC clusters depend on the angle of incidence and this tool provides means to correct the measurement errors accordingly, making use of a CSC cluster fitting tool.

Configuration

The tool is configured in python. Use the following to access the default instance:

from MuonClusterOnTrackCreator.DefaultMuonClusterOnTrackCreator import theMuonClusterOnTrackCreator

Package Managers

The MuonClusterOnTrackTool package is currently maintained by N. van Eldik and W. Liebig.
