We present our constraints on the dark matter distribution of this unusual system using Subaru and CFHT imaging data. Measuring a high S/N lensing signal from this cluster is potentially a challenging task because of its proximity to the Milky Way plane (|b|~5 deg). We overcome this challenge with careful observation planning and systematics control, which enables us to successfully map th","authors_text":"Andra Stroe, David Sobral, David Wittman, Henk Hoekstra, Huub Rottggering, Marcus Bruggen, M.
