Notes. Arguments have been grouped as a subset of parameters in horizontal bands. Parameters include the number of generated sources ngen, maximum timescale in terms of number of days ndays, and whether one is generating a repeater population (‘repeaters’). Number density parameters ρ include the number density model nmodel and cosmological parameters, Hubble constant H0, density parameter Ωm, cosmological constant ΩΛ, and finally maximum redshift zmax. Dispersion measure (DM) components include contribution from the host DMhost, from the intergalactic medium DMigm and from the Milky Way DMmw, each with a particular model and related parameters. DMtot reflects whether particular DM components are modelled or not. Furthermore, there is the emission range νemission, the isotropic equivalent bolometric luminosity in radio Lbol, spectral index γ, intrinsic pulse width wint and intrinsic time stamp tint, all with their respective modelling parameters. An empty space indicates that a particular argument was not required for the generation of that population. The final row does not show arguments, but instead indicates the relevant figures per population.
