[Rivet] Validation shows a problem with the CDF_2008_LEADINGJETS analysis

[Andy Buckley]

Hi all,

As you know, the Rivet 1.1.3 release has been delayed by about a month 
thanks to a collection of pesky bugs that have taken a lot of work to 
track down and fix. We're almost ready to go, though, and I've spent the 
last couple of days getting the 1.1.2 -> 1.1.3 validation runs working 
(just the UE analyses for now, more analyses will come later).

I was hoping these would be spotless and we could release today, but it 
looks like we have a problem in the CDF_2008_LEADINGJETS analysis, which 
now has much worse agreement with the data, especially in the 
max/min/diff trans region observables. Have a look:

We need to get this sorted asap. Hendrik, can you take a look please, 
and I'll get the bootstrap script re-written. We'll then re-run the 
1.1.3 validation once the problem is identified, and hopefully still get 
a release out in time for the Les Houches workshop to make use of it.

Andy
