Description

L1Algo: CA track finding algorithm

Core of the Cellular Automaton track finder (cat). The algorithm builds triplets of hits on neighboring stations, links them into track candidates, selects the best candidates, fits the tracks with the Kalman filter and extends them with the remaining hits.
