Surface brightness maps of the residuals after wavelet processing by DAWIS in each band. The orange contours show 3σ_bkg detection and the red ones 5σ_bkg. The white dots show the galaxies in the cluster redshift range (0.53 <  z <  0.56). From top to bottom and left to right: F435W, F606W, F814W, and F105W. The F105W residual map is smaller as a result of the WFC3 FoV being smaller than the ACS one, and has therefore been scaled to the other ones. The contours are smoothed with a Gaussian kernel of σ = 5 for the map to be readable.
