Fractional cumulative number distribution of FRB luminosities, $\stackrel{\sim }{N}(>L)$ against L, for the best-fit no-delay SFR model. The intrinsic population (hollow diamonds), follows the intrinsic luminosity index −1.58. The surveyed, detected sample (filled diamonds), however, is modified by the survey selection function, and follows a power-law with index −0.75 ± 0.02 (fit result shown). Grey crosses indicate the surveyed population that would follow from the Luo et al. (2020) Schechter luminosity function.
