Comparison of simulated frbpoppy and real frbcat distributions for FRB detections at Parkes. Left: dispersion measure distributions; right: fluence distributions for the same populations as the left-hand panel. frbpoppy simulations have been run on a Complex intrinsic FRB population, with the “parkes” survey modelled using the beam pattern as shown in Fig. 3. The p-value of a simple KS-test between both distributions is shown in the upper right corner of both panels. The product of these values showing the total goodness-of-fit is p = 0.51. The input parameters do not reflect the optimum values for the best fits between frbpoppy and frbcat distributions, but are merely an initial guess at some of the underlying parameters.
