virtual bool DTParametrizedDriftAlgo::compute	(	const DTLayer *	layer,
		const DTDigi &	digi,
		LocalPoint &	leftPoint,
		LocalPoint &	rightPoint,
		LocalError &	error
	)		const

virtual

First step in computation of Left/Right hits from a Digi. The results are the local position (in DTLayer frame) of the Left and Right hit, and the error (which is common). The center of the wire is assumed as hit coordinate along y. Returns false on failure.

Implements DTRecHitBaseAlgo.

virtual bool DTParametrizedDriftAlgo::compute	(	const DTLayer *	layer,
		const DTRecHit1D &	recHit1D,
		const float &	angle,
		DTRecHit1D &	newHit1D
	)		const

virtual

Second step. The impact angle is given as input, and it's used to improve the hit position (and relative error). The angle is defined in radians, with respect to the perpendicular to the layer plane. Given the local direction, angle=atan(dir.x()/-dir.z()) . This can be used when a SL segment is built, so the impact angle is known but the position along wire is not. NOTE: Only position and error of the new hit are modified

Implements DTRecHitBaseAlgo.

virtual bool DTParametrizedDriftAlgo::compute	(	const DTLayer *	layer,
		const DTRecHit1D &	recHit1D,
		const float &	angle,
		const GlobalPoint &	globPos,
		DTRecHit1D &	newHit1D
	)		const

virtual

Third (and final) step in hits position computation. In addition the the angle, also the global position of the hit is given as input. This allows to get the magnetic field at the hit position (and not only that at the center of the wire). Also the position along the wire is available and can be used to correct the drift time for particle TOF and propagation of signal along the wire. NOTE: Only position and error of the new hit are modified

Implements DTRecHitBaseAlgo.
