Same as Figs. 1 and 3 (Fe, O, Mg, and S, blue empty boxes), where we discard A 3526, M 87, and Perseus from the Fe average profile (top left), M 49, M 60, and NGC 4636 from the O average profile (top right), Perseus from the Mg average profile (bottom left), and NGC 1550 and Perseus from the S average profile (bottom right). These modified profiles are shown by the black squares.
