[Rivet] WFinder Missing Et

[James Henderson]

Hello,

I was implementing WFinder in my analysis using the afs setup at:
/afs/cern.ch/sw/lcg/external/MCGenerators_lcgcmt67b/rivet/2.2.0/x86_64-slc6-gcc48-opt/

I see that the missing eT cut is not respected by wfinder in that the 
constituentNeutrino eT is often well below the missing eT cut requested 
in the wfinder constructor.
Looking at 
/afs/cern.ch/sw/lcg/external/MCGenerators_lcgcmt67b/rivet/2.2.0/share/sources/src/Projections/WFinder.cc 
(lines 125-131) I see the missingET cut is applied on the scalar sum of 
the visible momentum in the event rather than on the missing momentum.

Should this cut not be applied to the transverse magnitude of the vector 
sum of the total event momentum rather than the scalar sum?

Thanks,
Jim
