Recall curves for each of the four morphologies as a function of the SPs’ injected S/Ns. The injected S/Ns for which the HTRU-North SP pipeline is complete are indicated by the coloured dash-dotted lines and entail ~11 for MI, ~10 for MII, ~14 for MIII, and ~ 11 for MIV. The morphology averaged recall is plotted with dashed black lines. The S/N above which the HTRU-North SP pipeline is considered to be complete, irrespective of a burst’s morphology, is ~11.
