Member Function Documentation

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), ...
