[Rivet] Transfer Functions

[Gavin Hesketh]

Hi,
for an upcoming ATLAS analysis, I'd like to apply some transfer 
functions to the theory curves. These take the form of a simple scale 
factor + uncertainty to be applied bin-by-bin (they vary across bins). 
It would be possible to provide the data in two forms (with and without 
transfers applied), but I would like to apply these functions to the MC, 
rather than to the data.

We will provide these transfers in HepData (with uncertainties), so I 
assume they could be loaded into the analysis routine as a histogram. 
Then run over some MC, and multiply together the resulting MC curves and 
the transfer function histograms.

I just wondered if anything like this is already being done in some 
rivet routines, or if anyone would have some suggestions on the best way 
to code it up?

thanks,
Gavin
