Comparison of cumulative distributions for simulated populations with best-fitting parameters and the CHIME/FRB Catalog 1 one-off FRBs. The S/N, w_eff and DM_total are shown in upper, middle and lower panels respectively. The population coloring is the same in all subplots. In the DM plot we also show the cumulative contributions of DM_host/(1 + z), and of the additional DM_IGM, for the delayed SFR model with 0.1 Gyr. These show how, for the lower-DM half of the population, these two components contribute roughly equally to the DM_total; while for the higher-DM half, the host contribution dominates.
