Member Function Documentation

virtual const FloatVec& EVENT::TrackState::getCovMatrix ( ) const

pure 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), ...

Implemented in IMPL::TrackStateImpl.

Referenced by main(), and UTIL::operator<<().

virtual float EVENT::TrackState::getD0 ( ) const

pure virtual

Impact paramter of the track in (r-phi).

Implemented in IMPL::TrackStateImpl.

Referenced by main(), and UTIL::operator<<().

virtual int EVENT::TrackState::getLocation ( ) const

pure virtual

The location of the track state.

Location can be set to: TrackState::AtIP, TrackState::AtFirstHit, TrackState::AtLastHit, TrackState::AtCalorimeter, TrackState::AtVertex, TrackState::AtOther

Implemented in IMPL::TrackStateImpl.

Referenced by IMPL::TrackImpl::addTrackState(), main(), UTIL::operator<<(), and IMPL::TrackStateImpl::TrackStateImpl().

virtual float EVENT::TrackState::getOmega ( ) const

pure virtual

Omega is the signed curvature of the track in [1/mm].

The sign is that of the particle's charge.

Implemented in IMPL::TrackStateImpl.

Referenced by main(), and UTIL::operator<<().

virtual float EVENT::TrackState::getPhi ( ) const

pure virtual

Phi of the track at the reference point.

See Also: getReferencePoint

Implemented in IMPL::TrackStateImpl.

Referenced by main(), and UTIL::operator<<().

virtual const float* EVENT::TrackState::getReferencePoint ( ) const

pure 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.

Implemented in IMPL::TrackStateImpl.

Referenced by main(), UTIL::operator<<(), and IMPL::TrackStateImpl::TrackStateImpl().

virtual float EVENT::TrackState::getTanLambda ( ) const

pure virtual

Lambda is the dip angle of the track in r-z at the reference point.

See Also: getReferencePoint

Implemented in IMPL::TrackStateImpl.

Referenced by UTIL::operator<<().

virtual float EVENT::TrackState::getZ0 ( ) const

pure virtual

Impact paramter of the track in (r-z).

Implemented in IMPL::TrackStateImpl.

Referenced by UTIL::operator<<().
