do you think you can still find the validation plots from back then?<br>

<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 moz-do-not-send="true"
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>
</div>
<div><br>

</div>
<div>Many thanks,</div>
