eta/pt pdg cuts for only particle not antiparticle

Hi,

This can not be done from the run_card, you will need to hack the code to do that.
In this case, the easiest is to hack the file
SubProcesses/setcuts.f and depending of what you want to do for the other cuts.
either set the e+ as not a lepton or just change the logic of the eta cut.

Cheers,

Olivier

Is there a straightforward way to make `eta_min_pdg` only apply to one of the particles/antiparticles, so that I can set the cuts for 11 and -11 to be different values?
