Notes. The results are derived assuming an elliptical NFW profile for the cluster-scale lens component and an elliptical dPIE for the galaxy scale halos. We report only the values that were optimised in the strong lensing fit; additionally, the coordinates of the cluster galaxies are listed in round brackets for the sake of clarity, but they were not optimised. The columns list the coordinates of the halo centroid (expressed in arcseconds with respect to the BCG centre: at the cluster redshift and for the assumed cosmology, 1 arcsec = 4.329 kpc), the potential ellipticity (here expressed as e = (a2 − b2)/(a2 + b2)), the halo position angle, the scale radius r   (that indicates the scale radius rs for the cluster-scale NFW halo and the truncation radius rcut for the galaxy-scale dPIE halos), the concentration parameter c200, the total mass M200, the characteristic velocity dispersion σ0 for the NFW or the dPIE profiles, expressed in km  s-1, the reduced χ2 (the number of degrees of freedom is enclosed within square brackets) and the root-mean-square computed in the image plane (rmsi). The uncertainties represent the 68% statistical errors, derived assuming a Gaussian probability distribution. If the upper and lower errors are significantly asymmetric we report both of them. For a description of the cases listed here, see Pag. .
