Interface TrackerHitPlane

All Superinterfaces:

Cloneable, LCObject, TrackerHit

All Known Implementing Classes:

ITrackerHitPlane

public interface TrackerHitPlane
extends TrackerHit

A tracker hit on a planar surface - the hit is stored as:
x,y,z, u(theta, phi), v(theta,phi), du, dv
where (x,y,z) is the position in global cartesian coordinates, u,v are the the meassurement directions (unit vectors, spanning the plane) and du,dv are the measurement errors along these directions. The order of u and v should follow the global cartesian coordinates x, y and z, e.g. in case of a plane parallel to the z-axis, u lies in the x-y plane and v is along z.

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::RTHPBIT_ID1)==1.
float	getdU() Measurement error along u
float	getdV() Measurement error along v
float[]	getU() Direction of first measurement - given as (theta, phi).
float[]	getV() Direction of second measurement - given as (theta, phi).
