All Tables

Table 1: Summary of the instrumental configuration used for the optical and near-IR observations of LBQS 1429-0053. The columns display respectively the date of observation, the telescope and instrument used, the filter, the image quality (IQ), and the total exposure time in kilo-seconds.
Table 2: Photometry of the objects in the 13 $^{\prime \prime }$ $\times$ 13 $^{\prime \prime }$ deconvolved field. The IDs correspond to sources identified in Figs. 1, 2, 3 and 4. The columns successively provide: (1) the object identification, (2-3) the coordinates relative to A, (4-7) the R, J, H and Ks magnitudes, (8-9) the redshift (spectroscopic redshift for A and B, photometric redshift for other objects) and the corresponding error bars, (10) some comments or references. The second line provides the date of observation, while the fifth line provides the magnitude differences between quasars A and B.
Table 3: Lower limit magnitude of detectability of a putative lensing galaxy according to its position (Cols. 2, 3 and 4). Column 5 displays the minimal redshift for an $\mathcal{L}^*$ galaxy of this magnitude.
