Constructor & Destructor Documentation

JCosineTarget()

JMARKOV::JCosineTarget::JCosineTarget ( JVersor3D  _target_dir )

inline

Constructor.

_target_dir is the direction where the photon has the highest chance to be detected.

Definition at line 386 of file JScatteringModel.hh.

getEfficiency()

double JMARKOV::JCosineTarget::getEfficiency ( JVersor3D  dir ) const

inlinevirtual

Return the efficiency, which is defined as the probability that a photon with the given direction hitting the target will be registered.

Note that we assume by convention that the direction is the PHOTON direction, NOT the direction that you would see the photon coming from!

By convention the highest efficiency is 1.

      return max( dir.getDot(target_dir), 0.0 ) ;
    }

getEffectiveArea()

virtual double JMARKOV::JTargetModel::getEffectiveArea ( )

Return the effective area, i.e.

the integral over the whole surface of the target, weighted by the efficiency.
