Overlay of the signal-to-noise ratio map of the WL mass reconstruction (shown as white contours starting at level S/N = 1.5 in steps of ΔS/N = 0.5) and a color image of the inner cluster regions, employing the HST F140W, F814W, and F606W images for the R, G, B channels. For the non-parametric mass reconstruction shown in this image, the positions of the WL centers were left free to vary. In contrast, for the mass constraints presented in Sect. 3.2.4 we fix them to the X-ray cluster centers. The two positions, as well as the BCG positions, agree well within ≲1σ. The cyan circle indicates the SZ centre from Bleem et al. (2015), while the magenta star marks the BCG of the western cluster component. The red contours show the smoothed X-ray MOS count-rate in steps of 1.385 × 10−5 cts.
