Detection accuracy of simulated FRB injections marginalized over individual parameters: (a) DM, (b) S/N, and (c) boxcar width (log-scaled). Each point represents the mean accuracy within a bin, with error bars denoting the 1σ uncertainty estimated from bin-level variation. The overall detection accuracy (99.12%) is shown as a dashed red line for reference. Panel a shows consistent accuracy across the DM range, while panel b highlights reduced performance at low S/N. Panel c reveals modest degradation in detection performance at both extremes of the width parameter space. These results characterize the completeness of the pipeline across key astrophysical and observational parameters.
