- I removed from the Digi file "r0327356667_v001_digi.root" downloaded from the data catalog all events between 81.3 and 84.6 seconds from the time stamp of the first event in the file (a total of 2609 events removed). The last event before the gap has eventID = 145973 and the first event after the gap has eventID = 159384. I also overwritten the livetime counter making it equal to the elapsed time counter (thus, deadtime = 0). This is saved in "data/r0327356667_digi_gaps.root".
- I removed from the Merit file the events with these IDs: 199996 (which is comprised between event 199993 and event 200002), 2000031 (which is comprised between event 200029 and event 200035), and all the events with 300544 < event ID < 300858. This is saved in "data/r0327356667_v001_merit_crashes.root".
- I inserted by hand two fake gaps in the digi Gap file, excluding events in these ranges of event IDs: 129504-181395 and 273973-280562. This is saved in "data/r0327356667_v001_digiGap_2gaps.txt"

As you can see the code stops when it encounter bins with livetime=0, and keep them isolated. Thus, even if the target bin time is 30 s, there is only one bin that long (# 15). The others are prematurely stopped because of the gaps. But, if we change the target binning to 5 s, much more bins will have the target duration:
