Hi,<br>
<br>
Peter, hg log tells me that you introduced the additional factor,
what was/is the issue?<br>

<div>Dear Rivet authors, </div>
<div><br>
</div>
<div>it looks like a bug has been introduced in the current
trunk version of the ATLAS inclusive jets measurement (the
version from the last release is fine). Specifically, the
normalisation factor in the finalise routine has been
modified:</div>

<div><a moz-do-not-send="true"
href="https://rivet.hepforge.org/trac/browser/src/Analyses/ATLAS_2014_I1325553.cc#L83">https://rivet.hepforge.org/trac/browser/src/Analyses/ATLAS_2014_I1325553.cc#L83</a><br>
</div>
<div><br>
</div>
to include an additional factor of 0.5 -- apparently to fix an
issue with the normalisation.
<div><br>
</div>
<div>There should be no such factor as absolute rapidity has
been used consistently throughout the analysis and such a
factor is only really necessary if absolute and signed
rapidities are being mixed (axis label vs cross section
differential).
<div><br>
</div>
<div>Note that the original version (without 0.5) has been
validated and no issues with the normalisation have been
observed, so I would recommend to unfix this again. :-)<br>
</div>

<div>Many thanks,</div>
