Public Functions

inline PhotonField()

virtual double getPhotonDensity(double ePhoton, double z = 0.) const = 0

returns comoving photon density [1/m^3]. multiply with (1+z^3) for physical number density.

Parameters:

ePhoton – photon energy [J]
z – redshift (if redshift dependent, default = 0.)

virtual double getMinimumPhotonEnergy(double z) const = 0

virtual double getMaximumPhotonEnergy(double z) const = 0

inline virtual std::string getFieldName() const

inline virtual double getRedshiftScaling(double z) const

returns overall comoving scaling factor (cf. CRPropa3-data/calc_scaling.py)

Parameters:: z – redshift

inline bool hasRedshiftDependence() const

inline void setFieldName(std::string fieldName)

inline size_t addReference() const

inline size_t removeReference() const

inline int removeReferenceNoDelete() const

inline size_t getReferenceCount() const

Protected Attributes

std::string fieldName

bool isRedshiftDependent

mutable size_t _referenceCount
