a–c The three cases based on the angular correlation between the 3 hits in an event. The origin of the visualized events is explained in the text. a The case when the sum of two smallest angles is greater than 180∘. b The case when sum is 180∘. c When the sum of two smallest angles is less than 180∘. d The measured scatter plot of the difference (β−α) vs the sum (α+β) of the two smallest angles
