That is correct.

The azimuthal part of the analysis includes the weights.
The fwd-bkwd part of the analysis does not include the weights.

We tested this only with unweighted events (Herwig++ & Pythia6) and 
compared to the results in the paper (there are no plots with MC having 
weighted events, so we would not be able to validate the code on 
weighted events anyway).

I'm not sure what is the preference here, but it seems to me that 
including the weights would require quite some changes to the code (I'm 
not the author of the analysis who wrote the analyzing part of the code 
and so it may take some time to do it).

Cheers,
   Roman
