Hmm, there is a scale attribute in the source files of the plots:<br>
<br>
E.g. in
<a href="http://cgutscho.web.cern.ch/cgutscho/ATLAS_2014_I1325553/d01-x01-y02.dat:" target="_blank">http://cgutscho.web.cern.ch/cgutscho/ATLAS_2014_I1325553/d01-x01-y02.dat:</a><br>

Can you find out what that Scale thing was for/from?<br>

do you think you can still find the validation plots from
back then?<span><font color="#888888"><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 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><br>
</div>
<div>Many thanks,</div>
