Subcomponent separation of FRB 20180916B multi-component bursts presented in Pastor-Marazuela et al. (2021). The top panel shows a histogram of the burst separation between discernible subcomponents in multi-component bursts. The mean A17 and A53 separations are shown as vertical dashed blue and yellow lines, respectively. The fit to a single lognormal and a double lognormal distribution are shown as solid and dotted black lines, respectively. The bottom panel shows the burst separations in each burst of the sample.
