Public Functions

inline IRB_Franceschini08()
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.

  • 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/
