        <br>
          So I was comparing the results with the latest version of
        Heriwg++ as part of our testing before the next release and we
        were much further off than I expected. After looking at the
        analysis and the paper I believed the paper was plotting d sigma
        /dy/dpT and the analysis d sigma/d|y|/dpT which differ by the
        factor of 1/2. I contacted Vojtech and he agreed it was wrong so
        I made the change.<br>
        <br>
          If it is wrong we can change it back<br>
        <br>
        Best Wishes<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><br>
              </div>
              <div><a href="https://rivet.hepforge.org/trac/browser/src/Analyses/ATLAS_2014_I1325553.cc#L83" target="_blank">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>
