Projected total mass versus ICL. The contours represent the smooth component of the lens model obtained with the 25 constrained systems. The yellow contour is obtained with a regular grid of 20 × 20 cells while the blue contour is obtained with a higher resolution grid of 25 × 25 cells. The image is a masked version of the F277W band, where the ICL light can be better appreciated. The contours correspond to values of the convergence, κ, computed at a fiducial source redshift of z_s = 3. Space between contours correspond to δκ = 0.1, with values starting at κ = 0.5. The last contour is for κ = 1.15. The white straight line marks the direction over which we constructed the 1D scan of the light profile and DM models.
