Oh Sorry, the label should be 1/N dNch/deta ofc as in the paper.

<div>Yes, we have always being doing it since the 900 GeV paper
I believe, which means we average the positive and negative
bins and plot this average on both the + and - corresponding
bins. So the normalisation is taken correctly. This means we
double the statistic of the measurements as there is no reason
to have different physics on both side ...</div>

Hi Xavier, Hannes,
I am having trouble understand the 13TeV pseudorapidity
distribution in the CMS_2015_I1384119 analysis.
In the rivet version, the ylabel says 1/N dN/deta which would
mean that the integral of the curve should be =1 --- however
it is more like 24.
I had a look into the paper to see if there is some normalisation
factor but found that there on Figure 3 the ylabel is not mentioning
a normalisation, i.e. it says dNch/d eta.
Could you please clarify what the normalisation of this histogram
is?
Thanks,
Holger
