Detailed Description

This header ties the generic definitions in this package.

The SegmentActsRefitAlg is designed to test the Acts tracking geometry & the global chi2 fitter at chamber level.

Added a flag in MuonConfig to turn off the R4 sTGC Digitization until fully validated.

: The sTgcMeasViewAlg takes all sTgcStrip, sTgcWire & sTgcPad measurements and pushes them into a common sTgcMeasContainer which is a SG::VIEW_ELEMENTS container

: The RpcMeasViewAlg takes the BI & legacy Rpc measurements and pushes them into a common RpcMeasurmentContainer which is a SG::VIEW_ELEMENTS container

: The MdtMeasViewAlg takes the MdtMeasurments && the MdtTwinMeasurements and combined them into a common MdtDriftCircleContainer

The MuonStripCsvDumperAlg reads the RpcStripContainer and dumps information to csv files The files are used for the algorithm development in acts.

Set of helper functions to fetch the links to the xAOD::MuonSimHits from the uncalibrated measurements.

MsTrackSeed represents the collection of segments that may be compatible with a muon track trajectory hypothesis.

copyright am arsch

the accumulator, and the peak finder.

To construct a seed, the segments are projected onto a cylinder which is roughly intersecting the middle stations of the spectrometer.

The links are decorated by the PrepDataToSimHitAssocAlg which is residing inside the MuonTruthAlgsR4 package. Before using these functions ensure that the algorithms are ran accordingly

Using FastDigi tool at the moment.

Uncalibrated xAOD measurements are collected from previously fitted segments and then passed through the global chi2 fitter. If the fit succeeded, a new xAOD::MuonSegment is created and the parameters as well as the hit summary are saved.

◆ getMatchingSimHits() [5/6]
