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.

Referenced by IMPL::TrackImpl::getCovMatrix().

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.
