Left: cluster time for exotic ($F_{+}>$ 0.97 and non-exotic ($F_{+}< $ 0.97) clusters. The additional peaks in the time distribution beyond $100$ ns arise from additional bunch crossings, which could not be rejected by the online Past-Future protection using the V0 detector. Right: difference in time of the most and second most energetic cell in the cluster for exotic and non exotic clusters. Both distributions are obtained for V2 clusters with energy in the interval $8 < E < 10$ GeV from data taken from pp collisions at $\sqrt{s}=13$ TeV.
