 Channel 0 has three consecutive hits: The second hit (time: t0,1) is processes as long as it is separated from the preceding hit (time: t0,0) by more than 160 ns (the conversion time); the third hit is not processed because it "arrived" to the MTDC after the matching window was closed. Channels 7 and 11 have a single hit each within the matching window. The resulting data structure is illustrated in the figure below: Channel 0 has three consecutive hits: The second hit (time: t0,1) is processes as long as it is separated from the preceding hit (time: t0,0) by more than 160 ns (the conversion time); the third hit is not processed because it "arrived" to the MTDC after the matching window was closed.
