Signal-to-noise ratio per kiloparsec annulus versus radius for clusters of varying halo mass (top), ICL effective radius (middle), and ICL Sérsic index (bottom) measured on the isolated ICL component (not including BCG) within 2 kpc annuli. The lines and shaded regions respectively show the median value and standard deviation of the S/N across nine instances of the same cluster simulated in different regions of the image. The vertical dotted lines indicate the 50–200 kpc region we selected for the annulus.
