[Rivet] Question about adding an ATLAS CONF note data points for comparison plots

[Deepak Kar]

Dear all,

Just chiming in here as an ATLAS insider. I see this is a heavy ion CONF
note, and if you go here:
https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/CONFNOTES/ATLAS-CONF-2012-119/
It says,
these preliminary results are superseded by the following paper:
HION-2012-07

So ideally you should be using the data from the paper, not the CONF (also
in principle ATLAS do not make CONF data points public). If that paper is
not in Rivet (I see the data points are in Hepdata), then of course you can
write your code, but may also be worth emailing ATLAS rivet contact
Christian Gutscow (added in cc) to check if anyone commited to doing it
from the collaboration.

Best,
Deepak
