I've copied in Chris Gutschow, who is now the main ATLAS Rivet analysis
support guy, as well as the non-ATLAS Rivet list in case your questions
are more generic.

Take a look in some existing ATLAS analyses -- that's usually the best
way to get a feel for how to set up jet inputs. It usually comes down to
setting up a FinalState to select particles within a given eta range,
then it's down to the analysis whether you use a VetoedFinalState to
exclude muons from that range, and whether you set the
FastJets::useInvisibles() method to declare that you want to include
neutrinos (Rivet vetos them by default).

That would be the DressedLeptons projection ;-)  Again, search through
existing analysis codes and you'll find plenty of good examples.
