Processed I_E image (left) and H_E image (right). The log-normal colour scheme is used to emphasise the ICL. We masked small, bright sources and interpolated over the masked pixels using a Gaussian kernel with a standard deviation of σ = 30 and 6 pixels for the I_E and H_E images, respectively. To guide the eye, we show the isophotal contours with a semi-major axis of a = 50 kpc (black) and 320 kpc (white).
