Constructor & Destructor Documentation

Pythia8PartonSelector::Pythia8PartonSelector

(

)

This is a Pythia8-specific parton selector that selects all status==71 or 72 partons. An explanation of the particle status codes returned by Pythia8 can be found in Pythia8 online manual (http://home.thep.lu.se/~torbjorn/pythia81html/ParticleProperties.html).
