Comparison between our 2D mass map (upper right) and the mass map obtained by B19 (upper left) for MACS J1206. Lower panel: we overplot the mass contours corresponding to both studies. The size of each panel is 101″ × 77″, centred on the cD galaxy. Contours are 0.05, 0.06, 0.1, and 0.13 × 10¹² M_⊙ arcsec⁻². Cyan ellipses represent the location of the three mass clumps proposed by B19, as in Fig. 3.
