[Rivet] Different binning of reference data and Rivet output

[Holger Schulz]

Hi,

I just noted that running Rivet with the UA5_1989 analysis
the binning of the resulting histos differs from those of the
reference histos in most of the cases (9 out of 12 observables).
The binning difference shows up in the AIDA files already.

The only obvious differences I could find are the encoding (UTF-8
for Rivet output and ISO-8859-1 for the ref data) and different
aida versions as well as different implementations.

Also the values are stored as "floats" in the case of the Rivet output,
while the ref data is stored as exponentials.

I guess none of the above should really be a problem, so I am a bit
puzzled at the moment. Do you have any idea where to look for
root of this problem?

Cheers
Holger
