Median 1σ radiant uncertainties in (top) right ascension and (bottom) declination as a function of the trajectory-fit cross-track RMS residuals. The values are binned logarithmically in RMS. the solid line in each colour-coded curve shows the median of all events in the bin, and the shaded region encloses the 5-95% percentile range (central 90%) and illustrates the event-to-event spread.
