Spatial distribution in the plane of the sky of the cluster members (black dots) with the corresponding isodensity contour map obtained with the 2D–DEDICA method (red contours). The black cross shows the position of the BCG, which is considered to be the center of A1213. The diagram is centered on the center of the cluster. A circle with a radius of 21′, i.e., approximately R₂₀₀, is drawn. The labels refer to the two peripheral 2D–DEDICA peaks listed in Table 3.
