◆ AddTRTMomConstr()

AddTRTMomConstr::AddTRTMomConstr	(	const std::string &	name,
		ISvcLocator *	pSvcLocator
	)

The AddTRTMomConstr is an implementation to add the so-called TRT momentum constraint on a track.

It was developed in the context of alignment, and its main idea is that if the TRT is free from "weak modes", its curvature measurement can be added as a PseudoMeasurement (PM) to a Si-only track. This extra information, taken into account while refitting the Si-only part of the track or read in by the alignment algorithms directly, can serve to eliminate the alignment weak modes from the Si tracker of ATLAS. More details can be found at: https://twiki.cern.ch/twiki/bin/view/Atlas/TRTMomConstraint
