Correct bin boundaries for histograms with integer content.
Histograms with integer content, e.g. number of tracks, number of PVs, etc., need to have their bins [n-0.5, n+0.5]
, and not [n, n + 1]
for the statistical numbers, e.g. the mean, not to be biased.
Two examples, one for HLT1 and one for HLT2 (where this is already done) are attached.
