SusyPlotter::mtWW, same impl as Anyes
drop old printouts; drop 'pass' from each line
htMin is always 200
d0S, mtwwMin, metRelMin: em is the same as me
SusySelection::sameSignOrEl: em is the same as me
also print the sum em+me
passNlepMin: also require that |eta_mu|<2.4

Details:
this is to take into account that we're using the 2L trigger, and the
muon trigger acceptance ends at 2.4.
We shoudl probably clarify this in the code structure, for example
defining a m_signalLeptons2L. Also, shouldn't this already be
accounted for in the trigger match?
