North is to the top, East is to the left. b) Same area, but with the PSF subtracted on components A and B (see Sect. 3.1 for details). c) Result of the MEM deconvolution (Sect. 3.2): A and B are the two quasar components. d) Result of the MCS deconvolution (Sect. 3.2). Two very red objects, VR1 and VR2 are identified to the North of component A in addition to the objects #1 to 5 (Sect. 4 and Table 2).

$\begin{figure} \par\includegraphics[width=10cm,clip]{H4186F4.eps} \end{figure}$ Figure 4: a) The 13 $^{\prime \prime }$ $\times$ 13 $^{\prime \prime }$ H-band field around LBQS 1429-0053 from HST/NICMOS2. A and B are the two quasar components. North is to the top, East is to the left. b) Same area, but with the PSF subtracted on components A and B (Sect. 3.1 for details). The faint objects identified in the field are objects previously identified as #1, 3, 4 and 5 , as well as three very red objects: VR1 and VR2 to the North of quasar A, and VR3, to the South (Sect. 4 and Table 2).

$\begin{figure} \par\includegraphics[width=8.3cm,clip]{H4186F5.eps}\hspace*{3mm} \includegraphics[width=7.9cm,clip]{H4186F6.eps} \end{figure}$ Figure 5: The left panel displays the number density isocontours for the magnitude range $23 \leq R < 25$ , superimposed on the FORS1 image. The coordinate (0,0) indicates the location of LBQS 1429-0053 A. The contours outline the regions of constant density. Labels of the contours display the number of galaxies per arcmin² (starting at 1 $\sigma$ , and then, 1.5 $\sigma$ , 2 $\sigma$ , 2.5 $\sigma$ , 3 $\sigma$ and 4 $\sigma$ ). The dashed square represents the ISAAC field-of-view. North is to the top, East to the left. The right panel shows the number of cells in the field which have a given galaxy density (galaxies per arcmin²). The Gaussian fits the points corresponding to cells which are assumed to be filled with background galaxies. The solid vertical line displays the mean galaxy density of the distribution, whereas the dashed and dotted lines are respectively at 1 $\sigma$ and 2.5 $\sigma$ .

$\begin{figure} \par\includegraphics[width=8.5cm,clip]{H4186F7.eps} \includegraphics[width=8cm,clip]{H4186F8.ps} \end{figure}$ Figure 6: The top panel shows the shear map for the 6.8 $^\prime$ $\times$ 6.8 $^\prime$ field-of-view around the quasars. Each stick displays the mean direction of galaxies in a cell of $30\hbox {$^{\prime \prime }$ }\times 30\hbox {$^{\prime \prime }$ }$ ( $\epsilon _{\rm max}=0.23$ ). The coordinates (218.125, -1.105) indicates the position of LBQS 1429-0053 A (black cross). The bottom panel shows the surface mass density from the maximum-entropy mass reconstruction. On this grey-scale,white corresponds to the lowest mass level, and black corresponds to the highest mass level. The contours successively outline regions of signal to noise: 0.3 (black dotted-dashed line), 0.6 (black dashed line), 1 (white dashed line) and 1.2 (white continuous line), the noise level being computed from the bootstrap sample.
