Subaru BVRIz composite color images centered on the galaxy cluster MACS1206 (z=0.439), overlaid with mass contours from our joint strong-and-weak lensing analysis of HST and Subaru observations. The image size in the left panel is 24 arcminutes (~8Mpc) on a side. The cluster is fairly centrally concentrated in projection, and associated with elongated large scale structure running north-east south-east, both in the projected mass and galaxy distributions.
