Detailed Description

Detector plane.

A detector plane is the principle object to define coordinate systems for track fitting in genfit. Since a particle trajectory is a one-dimensional object (regardless of any specific parameterization) positions with respect to the track are always measured in a plane.

Which plane is chosen depends on the type of detector. Fixed plane detectors have their detector plane defined by their mechanical setup. While wire chambers or time projection chambers might want to define a detector plane more flexibly.

This class parameterizes a plane in terms of an origin vector o and two plane-spanning directions u and v.
