Projected density distribution in the field A1204 (upper panel) and in the field of A2029 and A2033 (lower panel) obtained with the weak lensing analysis. The scale, marked at bottom left, is given in h₇₀   M_⊙   pc⁻². Red contours corresponds to a projected density above 3σ significance level (250 h₇₀ M_⊙ pc⁻² for A1204 and 400 h₇₀ M_⊙ pc⁻² for A2029/A2033) with steps of 50 M_⊙ pc⁻². X-ray contours are plotted in blue, the contour levels are (3, 5, 7, 9 and 12) times the rms noise. Red dots and green squares are the BCGs positions and the dynamical centres, respectively. Pink and light-blue points are the positions of the galaxies classified as members, for the primary and secondary component of A1204 and for A2029 and A2033, respectively.
