Implementation of the LCIO TrackState class.
| const FloatVec & IMPL::TrackStateImpl::getCovMatrix | ( | ) | const [virtual] |
Covariance matrix of the track parameters.
Stored as lower triangle matrix where the order of parameters is: d0, phi, omega, z0, tan(lambda). So we have cov(d0,d0), cov( phi, d0 ), cov( phi, phi), ...
Implements EVENT::TrackState.

| int IMPL::TrackStateImpl::getLocation | ( | ) | const [virtual] |
The location of the track state.
Location can be set to: AtIP, AtFirstHit, AtLastHit, AtCalorimeter, AtVertex, AtOther
Implements EVENT::TrackState.
| float IMPL::TrackStateImpl::getOmega | ( | ) | const [virtual] |
Omega is the signed curvature of the track in [1/mm].
The sign is that of the particle's charge.
Implements EVENT::TrackState.
| const float * IMPL::TrackStateImpl::getReferencePoint | ( | ) | const [virtual] |
Reference point of the track parameters, e.g.
the origin at the IP, or the position of the first/last hits or the entry point into the calorimeter.
Implements EVENT::TrackState.
