Constructor & Destructor Documentation

JOscFlux()

JAANET::JOscFlux::JOscFlux ( const JDiffuseFluxHelper &  diffuseFlux, const JOscProbHelper &  oscProb  )

inline

Constructor.

Parameters

diffuseFlux	diffuse flux function object
oscProb	oscillation probability function object

Member Function Documentation

is_valid()

bool JAANET::JOscFlux::is_valid ( ) const

inlinefinaloverride

Check whether this oscillated neutrino flux object is valid.

Returns

true if valid; else false

Definition at line 63 of file JOscFlux.hh.

    {
      return (F && F->is_valid() &&
              P && P->getParameters().is_valid());
    }

getFactor()

double JAANET::JOscFlux::getFactor ( const Evt &  evt ) const

inlinefinaloverride

Get flux for given event.

Note that in this evaluation the zenith-angle is defined
with respect to the line of sight (i.e. a neutrino pointing straight at you
from the center of the Earth has ).

Parameters

evt

event

Returns

flux
