Application of MuSCADeT to the MACSJ1149+2223 cluster. Top left: colour image generated using the F475W, F606W, and F814W bands. Our goal is to separate the foreground cluster galaxies (red) from the background lensed galaxy (blue). Middle: the two sources extracted with 2000 iterations of MuSCADeT. Bottom left: original image minus the blue source found by MuSCADeT. Bottom right: same as the bottom left, with the red source subtracted. Top right: residual image obtained after subtraction of the two estimated sources from the original data.
