In GeaneTrackRep::exptrapolateToPoca we set the origin of the resulting plane to result.GetOrigin(). Can you tell me what this point means?


It is the origin of the virtual detector plane as calculated during the propagation procedure (see FairGeanePro::FindPCA and FairGeanePro::Propagate(from parabola to parabola)) and for the propagation to closest approach to a POINT it is just the point itself (with respect to which the PCA is calculated).
