Note that there is a rather small number of entries in this histogram. This is because the new code changed the binning scheme for the 30s FT2 file, thus the old and the new sets of 30s file are often not comparable on a bin-by-bin basis. Indeed, start and stop times of the bins are most of the time different between the two sets. I do not know how to solve this issue... Interpolating is not an option, obviously.
