class EmissionMap : public Referenced

Particle Type and energy binned emission maps.

Use SourceEmissionMap to suppress directions at the source. Use EmissionMapFiller to create EmissionMap from Observer.

typedef std::pair<int, size_t> key_t
typedef std::map<key_t, ref_ptr<CylindricalProjectionMap>> map_t

Public Functions

EmissionMap()
EmissionMap(size_t nPhi, size_t nTheta, size_t nEnergy)
Parameters:

  • nPhi – number of bins for phi (0-2pi)

  • nTheta – number of bins for theta (0-pi)
