We apply a rest-frame ${\mu}_{B} = 25 \\mathrm{mag/arcsec^{2}}$ isophotal threshold to our clusters, belowwhich we define light as the ICL within an aperture of $R_{X,500}$(X-ray estimate of $R_{500}$) centered on the Brightest Cluster Galaxy(BCG). After applying careful masking and corrections for flux lossesfrom background subtraction, we recover $\sim$20% of the ICL flux,approximately four times our estimate of the typical background at thesame isophotal level ($\sim$ 5%). We find that the ICL makes up about$\sim$ 24% of the total cluster stellar mass on average ($\sim$ 41%including the flux contained in the BCG within 50 kpc); this value iswell-matched with other observational studies andsemi-analytic/numerical simulations, but is significantly smaller thanresults from recent hydrodynamical simulations (even when measured in anobservationally consistent way). We find no evidence for any linksbetween the amount of ICL flux with cluster mass, but find a growth rateof $2-4$ for the ICL between $0.1 <z <0.5$.
