Probability distribution of pulse width and broadening effects. Left panel: normalized distribution of intrinsic pulse width w_int, for the intrinsic, generated sample and for the surveyed, detected sample, the effective pulse width w_eff of this surveyed sample in the simulation, and of the CHIME/FRB Catalog 1 widths. Right panel: distribution of the simulated normalized t_dm and t_scat subcomponents of the width of the surveyed, detected FRBs; compared to the values from the CHIME/FRB Catalog 1. The sampling time t_samp of 0.98304 ms is marked with a dashed line. The population is generated using best-fitting values for the 0.1-Gyr delayed SFR model.
