All Tables

Table 1: Properties of the lensed quasar sample. Column 1: quasar name. Columns 2, 3: right ascension and declination of quasar image A (J2000). Column 4: quasar redshift. Column 5: lensing galaxy redshift, where "?'' means "unknown'' and "(p)'' means "photometric redshift''. Column 6: size of the system corresponding to the maximal angular separation between the quasar images (in arcsecond). Column 7: system configuration. Column 8: predicted value of the external shear strength and position angle of the shear ¹ Lehár et al. (2002), ² Saha & Williams (2003), ³ Lopez et al. (1998), ⁴ Rusin et al. (2001). The symbol "-'' means that the system has never been modeled.
Table 2: FORS1 and ISAAC observations. Column 1: quasar name. Column 2: filter. Column 3: total exposure time in ks. Column 4: field of view used for the analysis.
Table 3: WFPC2 observations. Column 1: quasar name. Column 2: filter. Column 3: proposal P.I. and proposal ID. Column 4: total exposure time (in ks).
Table 4: Characteristics of the galaxy number overdensities. Column 1: quasar name. Column 2: limit for the galaxy catalog (said to be as complete as the FDF galaxy catalog where the curves in Fig. 1-top join). Column 3: magnitude range over which we can study the significance of the galaxy overdensity. Column 4: position of the center of the galaxy number overdensity relative to quasar image A (see Figs. 3 and 4). The uncertainty of the exact position of the galaxy overdensity is about 5 $^{\prime \prime }$ . Column 5: galaxy density at the location of the galaxy overdensity center. Column 6: FDF mean galaxy density in the magnitude range given in Col. 3. Column 7: FDF maximal galaxy density in the same magnitude range. Column 8: detection level (in $\sigma$ ) of the cluster compared to the FDF mean galaxy density level. Column 9: detection level of the cluster (in the magnitude range given in parentheses) above the galaxy background level measured in the same frame.
Table 5: Results of the weak-shear analysis and of the mass reconstruction. Column 1: quasar name. Column 2: number of galaxies per arcmin² corresponding to the galaxy overdensity. Column 3: position of the galaxy overdensity center relative to the quasar images. Column 4: photometric redshift of the galaxy overdensity and corresponding error bar ("^*'': value inferred from previous paper, see text for references). Column 5: magnitude range for the background galaxies used for the weak-shear analysis. Column 6: number of galaxies used for the weak-shear analysis and the mass reconstruction. Column 7: ICF width of the mass reconstruction in arcsecond. Column 8: upper limit of the mass integrated from the mass reconstruction in a radius of 500 kpc and centered at the galaxy group position. Column 9: galaxy cluster velocity dispersion corresponding to the mass given in Col. 8. Column 10: shear orientation in degree.
Table 6: Galaxy group masses. Column 1: quasar name. Column 2: mass integrated in the original mass map, in a radius of 500 kpc centered on the galaxy overdensity. Column 3: lower mass value reconstructible by LensEnt2.
