<div> Hi Holger,</div>
<div><br>
</div>
<div> another subject : I am running Pythia8 with helix to fix
fragmentation parameters on DELPHI_1996_S3430090</div>
<div> and I found couple of problems there </div>
<div><br>
</div>
<div> 1/ the data are not consistent : the inclusive spectra are
supposed to be normalized to the measured charged multiplicity</div>
<div> but there is a small difference ( plot 35, the measured N_ch
gives 20.92 , but the normalization of inclusive spectra is done
to 21.05 )</div>
<div><br>
</div>
<div> 2/ the plot 8, ln(1/x) has wrong normalization altogether -
the integral gives just 19.94, i.e. 5.5% below the integral for
other plots.</div>
<div><br>
</div>
<div> The MC processed through corresponding rivet analysis has the
normalization as expected, i.e. integrals of inclusive spectra
correspond</div>
<div> to value of d35_x01_y01.</div>
<div><br>
</div>
<div> I think the data ( minimally for d08_x01_y01) should be
corrected - I know people who worked on the paper (Klaus
Hamacher,...).</div>
<div><br>
</div>
<div> This plot allways gave bad chi2, that's how I found out.</div>
<div><br>
</div>
<div> What do you think ? The impact on fits is visible (
better chi2 after correction )</div>
<div><br>
</div>
<div> cheers,</div>

<div>are we talking about plots.pdf file attached to your
first mail today (168kb) ? it contains not-so-well
reproduced b-jets plots,</div>
<div>not the power spectra from azimuthal ordering ... can
you please send them once more ?</div>
<div><br>
</div>

<div> yes, but for b-jets ! I guess the rivet
analyses got mixed in your files.</div>

??? I copied the routine ATLAS_2012_I1091481<br>
from your public, was that wrong? The plots I sent
show the same<br>
distributions as are shown <a moz-do-not-send="true"
class="moz-txt-link-freetext"

Is that wrong?<br>

<div> Yes, for azimuthal ordering one should run
full minbias+diffractive mixture</div>

<div> hi Holger,</div>

</div>
<div> thanks for the trimming option - but
the plots are not from the azimuthal
ordering ?</div>

It's a private run of Pythia8 just 10k events.<br>
