	)

pure virtual

Function for getting a drift length estimation.

Parameters

tdcCount	This is the "drift time" saved in the CDCHit. Actually it can be the sum of various effects such as trigger time jitter, propagation time of the signal in the wire of the CDC etc. Actual translators should however get the appropriate drift length including the specified effects.
wireID	Object to identify hit wire.
timeOfFlightEstimator	This is an estimator for the time, that lies between the event time/ time of creation of the particle and the time at which the ionisation happened, which is the starting point for the calculation of the drift length/actual drift time.
ambiguityDiscriminator	Information to resolve left/right ambiguity.
z	z-position for determining the in-wire-propagation time.
alpha	Track incident angle in r-phi plane.
theta	Track incident angle in s-z plane (=polar angle).
adcCount	ADC count.

Returns: Best estimation of closest distance between the track and the wire.

virtual double getDriftLengthResolution	(	double	driftLength = `0.`,
		const WireID &	wireID = `WireID()`,
		bool	ambiguityDiscriminator = `false`,
		double	z = `0`,
		double	alpha = `0`,
		double	theta = `static_cast< double >(TMath::Pi()/2.)`
	)

pure virtual

Uncertainty corresponding to drift length from getDriftLength of this class.

Parameters

driftLength	Output of the getDriftLength function.
wireID	Encoded sense wire ID.
ambiguityDiscriminator	Information to resolve left/right ambiguity.
z	z-position for determining the in-wire-propagation time.
alpha	Track incident angle in r-phi plane.
theta	Track incident angle in s-z plane (=polar angle).
