Median signal for row 16, showing dispersion-direction pixel position on the x-axis, and received signal in DN on the y-axis, for the first (top panel) and fifth (bottom panel) group. The solid black line denotes the full-well value, while the dashed black line marks the 60 % saturation threshold. The blue shaded area indicates the range in dispersion direction that falls above the 60 % saturation threshold.
