EVENT::TrackerHitPlane Class Reference

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. More...

Detailed Description

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.
