[Brahms-dev-l] Acceptance Weighting for dAu and pp at Forward

Hi,
 
As we all know, picking up a right acceptance map 
for a given z at small angle is tricky due to a limited 
accuracy on determining the origin of the track.  
it's especially an issue for dAu and pp data since 
BB vertices are available only for a fraction of event.  
 
Here is what I believe one of  the ways to accommodate 
the uncertainties in applying z dependent acceptance weight. 
This method doesn't require generating new maps and 
has been "successfully"  adapted in the Ramiro's analysis. 
 
Cheers, JH
