[Rivet] Binning mismatch [Re: Bug in H1_2000_S4129130?]

[Ben Waugh]

Hi Andy, All,

The issue with the binning seems to be due to the fact that there is a 
gap between eta of -2 and -1 in the published data. Presumably this is 
related to the detector acceptance. The Rivet analysis does include a 
bin in this region,
and compare-histos doesn't like the fact that the bins are different.

We should think about how compare-histos should deal with this 
situation, but I don't think there is anything (obviously) wrong with 
the Rivet analysis.

Cheers,
Ben
