Run 7241 had besides peaks at -3.4 and 0.1 µs in GPS1-GPS2 as nearby runs also some worse features with 61 underflows and 683 overflows in the diagram (i.e. outside the range -10 µs to 10 µs, see plots). Inside the ±10 µs interval there is a peak at -3.4±0.1 µs with 650993 events, a peak at 0.1±0.1 µs with 83019 events and 1 event with +3.2 µs. Details on the 61 underflows and 683 overflows are given below.
