I'm not sure which dataset you mean. Are you saying that the data used
to be in Hepdata but was removed for inconsistencies?

In this particular case Peter suspects ALEPH_2001_S4656318 uses a
dataset that was used for a Herwig++ internal analysis before we
converted those to use Rivet. The source of the original analysis is
Stefan Gieseke, I'll ask him.

I agree with this as the general rule. It also looks like
ALEPH_2001_S4656318 is the only exception to that rule we have so far,
so maybe we can manage that one by hand for now.

See you,
