Interface TrackerHitZCylinder

All Superinterfaces:

Cloneable, LCObject, TrackerHit

All Known Implementing Classes:

ITrackerHitZCylinder

public interface TrackerHitZCylinder
extends TrackerHit

A tracker hit on a cylindrical surface that runs parallel to the z-axis - the hit is stored as:
x,y,z, center(x,y), dRPhi, dz
where (x,y,z) is the position in global cartesian coordinates, center(x,y) is the center of the cylinder and Rphi and z are the measurement errors. Note the radius of the cylinder is given by R=sqrt( dx^2c+ dy^2 ) and dx=x-x_c, dy=y-y_c.

Method Summary

Modifier and Type	Method and Description
int	getCellID0() Same name as in CalorimeterHit, even though there are no 'cells' in this case
int	getCellID1() Same name as in CalorimeterHit, even though there are no 'cells' in this case Optional, check/set flag(LCIO::RTHZBIT_ID1)==1.
float[]	getCenter() Center of cylinder in RPhi-plane - given as (x,y).
float	getdRPhi() Measurement error along RPhi
float	getdZ() Measurement error along z
