Member Function Documentation

bool Smear::PlanarTracker::Accepts ( const erhic::VirtualParticle & p ) const

virtual

Returns true if the particle falls within the angular acceptance defined via the input parameters. This is defined as the particle's transverse path length being greater than half of (outer radius - inner radius) / number of fit points i.e. the particle has to pass through enough of the detector to cause at least one measureable point.

Implements Smear::Tracker.

Definition at line 160 of file PlanarTracker.cxx.

PlanarTracker * Smear::PlanarTracker::Clone ( const char * = "" ) const

inlinevirtual

Returns a new copy of this Tracker. The argument is not used.

Implements Smear::Smearer.

Definition at line 124 of file PlanarTracker.h.

TVector3 Smear::PlanarTracker::ComputeIntersectionWithRadius	(	const erhic::VirtualParticle &	p,
		double	radius
	)		const

protected

Compute the intersection point of the particle with a radial surface. Returns the 3-vector of the intersection point if the z of the intersection is within (zmin, zmax) of this detector, or (0, 0, NaN) if not.

Definition at line 74 of file PlanarTracker.cxx.

double Smear::PlanarTracker::GetThetaMax ( ) const

virtual

Returns the maximum theta of particles accepted by the tracker (radians).

Implements Smear::Tracker.

Definition at line 66 of file PlanarTracker.cxx.

double Smear::PlanarTracker::GetThetaMin ( ) const

virtual

Returns the minimum theta of particles accepted by the tracker (radians).

Implements Smear::Tracker.

Definition at line 58 of file PlanarTracker.cxx.

double Smear::PlanarTracker::L ( const erhic::VirtualParticle & p ) const

virtual

Returns the path length of the particle through the tracker in metres.

Implements Smear::Tracker.

Definition at line 100 of file PlanarTracker.cxx.

double Smear::PlanarTracker::LPrime ( const erhic::VirtualParticle & p ) const

virtual

Returns the transverse path length of the particle through the tracker in metres.

Implements Smear::Tracker.

Definition at line 124 of file PlanarTracker.cxx.

int Smear::PlanarTracker::NPoints ( const erhic::VirtualParticle & p ) const

virtual

Returns the number of measurement points for the particle. This is the number of planes hit in the planar tracker for the particle.

Implements Smear::Tracker.

Definition at line 143 of file PlanarTracker.cxx.

void Smear::PlanarTracker::Print ( Option_t * = "" ) const

virtual

Print information about this device to standard output.
