Pattern Recognition

The pattern recognition code is designed to associate hits in one or more detector to a single track.

The pattern recognition provides an estimate of the trajectory of the track and the covariance matrix, but does not attempt to do an accurate fit. A later fit is done using the Kalman filter after all hits have been associated to the track, which does attempt to get the best possible track parameters.

Monitoring of Pattern Recognition

In the default Brunel options, the PatChecker algorithm is run from the PatChecker package.
