[Rivet] missingEt variable in WFinder constructor

[Inês Ochoa]

Dear Rivet developers,

I am using Rivet 2.1.1 and selecting a W candidate with WFinder. I am 
applying a cut on the missing Et (as one of the arguments of WFinder()) 
but when accessing the neutrino with constituentNeutrinos()[0] I see 
that there is no cut on its Pt. In fact, changing the MET cut on the 
WFinder constructor seems to have no impact on the resulting number of 
events.

Is this a known problem? Should that argument be ignored and the cut 
applied on the constituentNeutrino object instead?

Thanks!
Inês
