Hi David and Andy,

Many thanks!
I see the cuts on the first jets are pretty hard (50-60GeV - lines
121-133), however, the jet multiplicity is filled after the 30GeV cut only.
Does the jets reconstructed according to:
https://rivet.hepforge.org/trac/browser/src/Projections/FastJets.cc.

Thanks
Liron
