Cumulative distribution of the S/Ns and fluences of FRBs in the SFR model. On the right ordinates, the number N detectable/detected for CHIME. On the left ordinate, the fraction of this number over the total, $\stackrel{\sim }{N}=N/N_{\mathrm{total}}$. Left panel: plot of N(> S/N) versus S/N. The two simulated populations, surveyed with different SEFD_eff, are shown with cross and circle markers, while the CHIME/FRB Catalog 1 is represented using star markers. The S/N “underlying” distribution is generated using a threshold below the minimum range of this plot. The intrinsic and both surveyed populations have the same slope, indicating a scale-invariant feature despite selection effects and different telescope sensitivity. The vertical dash-dotted lines mark the S/N for the CHIME/FRB S/N threshold and for the start of the high-S/N deviation from our surveyed populations, respectively. Right panel: N(> F)−F plot. The surveyed population with different SEFD_eff and CHIME/FRB Catalog 1 are shown in triangle down, triangle up and star markers respectively; the linear fit to surveyed population SEFD_eff ∼ 90 Jy has a slope −1.30 ± 0.01. The vertical dashed line at 5 Jy ms marks the lower bound used in our comparison of fluence distributions.
