J2000.0 coordinates of the main galaxy populating the deflector; spectroscopic redshift $z_{\rm spec}$; photometric redshift $z_{\rm phot}$; Einstein radius derived from the strong lensing modelling, when possible. For the non cusp group, we report with a ~ the distance between the lensed feature and the brighest group member; Einstein radius derived from fitting a Singular Isothermal Sphere (SIS) to the weak lensing signal; mean geometrical factor $D_{\rm ls}$/$D_{\rm s}$ and corresponding effective redshift  $z_{\rm eff}$; velocity dispersion; projected mass derived from weak lensing computed within a circular aperture of radius equals to 2Mpc, in units 1014 $M_{\odot}$(masses derived using the Coupon et al. (2008) photometric redshift catalogue are given within brackets); density of background galaxies, expressed in objects per square arcminute; total i band rest frame luminosity corrected for evolution, in units 1012 $L_{\odot }$; seeing of the i band observations; i band completeness magnitude. Einstein radii and seeings are expressed in arcseconds.
