Lensing results for CL 1357+6232. Upper panel: MegaCam r′-band image (cut-out of  ~20′ side length), overlaid with S-statistics (orange solid) and (green dashed) contours. Contours start at S = 1.0 and , with increments of ΔS = 1.0 and , respectively. The eight-pointed star symbol marks the ROSAT cluster centre, while the filled square shows the shear peak grid cell. A star symbol with error bars denotes the lensing centre from bootstrapping. Regions inside red polygons are masked out of the analysis. Lower left panel: profiles of the binned tangential (⟨ ε_t⟩, filled circles) and binned cross (⟨ ε _× ⟩, open diamonds) ellipticities. Error bars give the bin dispersions. The thick blue curve denotes the best-fit NFW model (Eq. (3)). Here, the S-peak was assumed as centre. Lower right panel: Δχ²(r₂₀₀,c_NFW) with respect to its minimum (filled circle), shown as grey shading and contours indicating 1σ, 2σ, and 3σ confidence. An upward (downward) triangle on a dashed (dash-dotted) curves mark the best-fit values assuming the B01 and B12 mass-c₂₀₀-relations. A diamond marks cluster parameters assuming the S-peak as centre.
