Caption: Figure 6.
The top row shows the timing residuals plotted against the peak flux density and fluence. We note that across both timing residual figures, there is a clear separation between two distinct emission modes, as indicated by both intrinsic brightness and residuals. The bottom row shows histograms of the peak flux and fluence. The histograms appear bimodal; however, these histograms are not corrected for the complex selection effects of the CHIME/FRB system.
