Class Documentation

class TabularPhotonField : public PhotonField

Photon field decorator for tabulated photon fields.

This class reads photon field data from files; The first file must be a list of photon energies [J], named fieldName_photonEnergy.txt The second file must be a list of comoving photon field densities [1/m^3], named fieldName_photonDensity.txt Optionally, a third file contains redshifts, named fieldName_redshift.txt

Public Functions

TabularPhotonField(const std::string fieldName, const bool isRedshiftDependent = true)

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

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 getRedshiftScaling(double z) const

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

Parameters:

z – redshift

virtual double getMinimumPhotonEnergy(double z) const

virtual double getMaximumPhotonEnergy(double z) const

inline virtual std::string getFieldName() const

inline bool hasRedshiftDependence() const

inline void setFieldName(std::string fieldName)

inline size_t addReference() const
