Sample of a few galaxy clusters processed by DAWIS. The clusters are at z = 0.3, and the input ICL profile parameters are r_e = 100 kpc and . First column: input ICL profiles. Second column: cluster images with ICL and galaxies, but without noise. Third column: cluster images with noise, called GAL+ICL+NOISE images in the text. Fourth column: total denoised image restored by DAWIS. Fifth column: residuals image, which is the difference between the GAL+ICL+NOISE image and the DAWIS restored image. Sixth and seventh columns: restored images containing atoms classified as galaxies and ICL, respectively (see details in Sect. 5.3). The intensity scale is the same for columns 2, 3, 4, and 6, but the contrast is greatly enhanced for columns 1, 5, and 7.
