template<typename It >

static marley::IteratorToMember<It, FitParameters> evgen::MarleyTimeGen::TimeFit::make_FitParameters_iterator ( int  pdg_code, It  iterator  )

inlinestatic

Converts an iterator that points to a TimeFit object into an iterator that points to the appropriate (based on the neutrino PDG code) FitParameters member owned by the TimeFit object.

This function helps us to be able to sample time bins with a std::discrete_distribution using the bin luminosities without redundnant storage.

Parameters

pdg_code	PDG code for the neutrino type of interest
iterator	An iterator to a TimeFit object that will be converted

double evgen::MarleyTimeGen::TimeFit::Time ( ) const
