Up: 15′ × 15′ inset of the cluster field extracted from the full r′ MegaCam image. The thick red contours show the mass distribution derived from the 2D weak-lensing analysis. The contour levels are linearly spaced in σ of the mass reconstruction, starting at 2σ. The thin blue contours come from the X-ray map obtained with XMM-Newton. The image was filtered with wavelets and the contours are scaled logarithmically. Bottom left: same mass isocontours overlaid on the galaxy luminosity distribution where cluster members are selected within the cluster red sequence and m_r< 23. Bottom right: true colour image of the cluster centre from g′, r′, i′ combination. The field of view is 3′ × 3′.
