[Rivet] histogram normalization for a CMS analysis

[Albert Knutsson]

Dear Rivet developers,

we are about to finish a Rivet plugin for "Measurement of BB Angular 
Correlations"
http://cdsweb.cern.ch/record/1329400/files/BPH-10-010-arxiv.pdf

We are a bit unsure about how to do the normalization of the MC in the 
Rivet plugin.

In the publication only a shape comparison is made: The MC is normalized 
to the data in a certain region, and a 47% common systematic 
normalization error is not included on the data points.

Would you prefer to have the MC in the rivet plugin normalized as in the 
publication (for shape comparison)?

or

Would you prefer to have a MC cross-section prediction from the plug-in?
47% uncert extra uncert then need to be added on the points in the data 
aida-file.


Thanks and cheers,
Albert on behalf of CMS

ps. Fig. 6 in the publication is the relevant one
pss. the aida-file in the hep data base does not include the 47% 
normalization error
