Hi Holger,
<div class=""><br class="">
</div>
<div class="">there are cases where the Rivet reference data values and the HEPData reference values will be different because e.g. there’s a note on HEPData saying the central values ought to be shifted by some factor in order to account for the the final
luminosity calibration for the respective year (which hadn’t been available when the HEPData entry was made public).</div>
<div class=""><br class="">
</div>
<div class="">Cheers,</div>
<div class="">Chris</div>

<p class="">Hi,</p>
<p class="">I wrote a script that does some trivial checks for the reference<br class="">
data files shipped with rivet and their counterpart obtainable from<br class="">
HepData.</p>
<p class="">It generates reports which can be found here:<br class="">

<p class="">There is quite a number of inconsistencies.</p>
<p class="">Quite often in LHC analyses the dxy tags differ, a number of <br class="">
ref data sets differ in the number of data points between rivet and hepdata<br class="">
and of course there are several analyses where the data is not in hepdata<br class="">
at all.</p>
<p class="">And then there are some "goodness of fit" issues where I compare<br class="">
two scatters as such (can clearly be improved):</p>

<blockquote class="">def gof(P1, P2):<br class="">
chi=0.0<br class="">
for num, p in enumerate(P1):<br class="">
chi += (p.y - P2[num].y)<br class="">
chi += (p.yErrAvg - P2[num].yErrAvg)<br class="">
chi += (p.x - P2[num].x)<br class="">
chi += (p.xErrAvg - P2[num].xErrAvg)<br class="">
return chi<br class="">

<p class="">So yeah I don't really know what course of action to take but it seem quite clear<br class="">
that HepData and rivet have diverged quite substantially.</p>
