Here I present the comparison between the files produced during P130 and the old files, archived in the astro server and produced with the old code.
All plots refers to 1s FT2 files, unless otherwise stated.
For each quantity q in the FT2 file I report a histogram of the fractional difference between the "new" FT2 file (from P130) and the "old" one (from the archive): (qNEW-qOLD)/qOLD.

As you can see, differences are distributed around zero, with maximum differences of the order of few percent most of the time, except for some exceptional cases. Thus, they should cancel out when merging the 1s bins in the 30s ones.
Indeed, this is the histogram of the fractional difference in LIVETIME for 30s FT2 files:
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 very first runsthe 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 different between the two sets. I do not know how to solve this issue... Interpolating is not an option, obviously.
