Examination of the effects on the detectability of SPs when searched for with a limited set of boxcar widths. The injected S/Ns of all injected SPs are plotted against their discrete injected S/N. The width difference between the best-fitting boxcar width and the actual propagated burst width of an SP is indicated by the plotted marker sizes. The scattering time (referenced to 1 GHz) with which it is injected is represented by the marker colours and the marker symbols, which depict the number of subcomponents an SP is composed of. The dotted red lines indicate HEIMDALL’s S/N search threshold of 6.5, and the number of SPs in each quadrant of the plot is given by the red numbers in the corners.
