Smoothed KS statistic measured over SFE using the 2D-Bound settings (See Table 2) for upper luminosity limits of 120 L_⊙ (top) and 55 L_⊙ (bottom). The smoothing window is SFE = 0.01%. The median value is plotted with an opaque line, and the shaded regions show the 16th and 84th percentile of the integrated values. The critical KS statistic (calculated with Eq. (9)) is shown by the black line.
