This algorithm aims at rejecting multi-track events and it corresponds to a cut on the number of CHOD slabs fired in time with respect to the L0 trigger.

The cut tested on 2014 data (run 1520) is: NSlabs < 6 (see pag 23 here). The algorithm efficiently rejects multi-tracks and pipi0 with photon conversions.

The algorithm has been deployed on NA62 PC-farm during 2015 run.
