ICL mass fraction as a function of cluster mass, considering overdensities of 500 (top) and 200 (bottom). The lines show the median values and the shaded regions the 16th–84th percentiles. Results are shown for both GADGET-X (green solid line) and GIZMO-SIMBA (magenta dash-dotted line). Note that the scale is the same for both plots in the Y-axis, but different for the X-axis.
