A track seed is made for every tpc seed. Not every tpc seed has a silicon match, we skip those cases completely in pp running

Need to also check that the tpc seed wasn't removed by the ghost finder

If using directed navigation, collect surface list to navigate

Reset the track seed with the dummy covariance

Set host of propagator options for Acts to do e.g. material integration

Check that the track fit result did not return an error

Track fit failed, get rid of the track from the map

Acts::BoundSquareMatrix PHActsTrkFitter::setDefaultCovariance ( ) const

private

Acts cares about the track covariance as it helps the KF know whether or not to trust the initial track seed or not. We reset it here to some loose values as it helps Acts improve the fitting. If the covariance is too loose, it won't be able to propagate, but if it is too tight, it will just "believe" the track seed over the hit data

If we are using distortions, then we need to blow up the covariance a bit since the seed was created with distorted TPC clusters

Acts takes this value very seriously - tuned to be in a "sweet spot"
