The Atlas setup won't use any of the RivetGun params files, since the  
generator is steered by Athena.  I could certainly run several jobs  
for different ckin(3) and ckin(4) but then the problem becomes merging  
them properly.  I think you need the dsigma/dPT of the leading jet in  
order to know the contribution from each plot.  Might it be worth  
adding that plot to the analysis in future for that reason?

If I remember correctly, the data is split up into a min bias sample  
and a PT>20GeV sample anyway.  So I could take the min bias plots from  
a low ckin(3) sample and the pt 20 plots from a ckin(3) around 15 or  
so.  Running in RTT I think we'll be limited to ~100k events (I think  
there are ~10 cpus spread over all the RTT jobs over 24 hours).  Of  
course we can have as many as we like from our own batch system.
