[Rivet] HepData and Rivet growing apart

[Holger Schulz]

Hi riveteers and Graeme,

I have noticed that the data stored in hepdata and their equivalent in rivet
are diverging quite a bit. This mail is just a report I do not have any
suggestions
but would like to remind everyone that this problem exists.

Not only are the histokeys quite different in the sample I checked but
also the
binning and the numerical precision of central values at times can
differ quite
a bit. Further, new analyses don't seem to make it into hepdata even
after half a
year or so (e.g. ATLAS_2017_I1509919).

I was toying with the in principle very helpful yodastat download link
that gives
you the yoda files with statistical errors only and is hence desirable for
more in depth statistical analysis. But due to the inconsistencies it
cannot be
used without great pain.

If you want to have a look, I checked this entry:

against

    https://rivet.hepforge.org/hg/rivet/file/6375cc481dd0/data/refdata/ATLAS_2011_S8994773.yoda


Any thoughts and discussions are welcome.

Thanks,
Holger
