7.3.1. \(\tt -e0\): Cosmic distances

Computes the cosmological comoving, angular diameter, and luminosity distances, as well as the \(\Omega\) and Hubble parameters at \(z > 0\):

7.3.3. \(\tt -e2\): Luminosity and multi-level boosts

Computes \(c_{\Delta}(M_{\Delta},z)\), the luminosity \(\mathcal{L}(M_{\Delta},z)\), and the boost, \(\mathcal{L}_{\rm halo\,substructure}/\mathcal{L}_{\rm no\,substructure}\), over a user-defined mass range of extragalactic halos.

7.3.5. \(\tt -e4\): EBL absorption

Computes the \(\gamma\)-ray EBL absorption exponent, \(\tau(z,\,E_\gamma)\), and \(e^{-\tau(z,\,E_\gamma)}\) by a polynomial fit in energy dimension and log-linear interpolation in redshift \(z\) to tabulated values from the literature
