Conclusion

The package OTR/ITR-CATS was developed for the reconstruction of tracks in the Pattern Tracker of the HERA-B experiment. The reconstruction algorithm implemented in the package is based on a cellular automaton for track searching and the Kalman filter for track fitting. Comprehensive tests of the package have shown remarkably high reconstruction efficiency, good accuracy of track parameter estimates, a reasonable behavior of CPU time consumption and robustness of the algorithm with respect to large track multiplicities.
