Notes. Listed are the number of generated sources ngen, maximum timescale in terms of number of days ndays, and whether 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 energy density due to the cosmological constant ΩΛ, number density parameter α, as well as the maximum redshift zmax. Dispersion measure (DM) components include a contribution from the host DMhost, the intergalactic medium DMigm, and 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 si, and intrinsic pulse width wint, all with their respective modelling parameters. An empty field indicates that a particular argument was not required for the generation of that population.
