Appendix A: Presentation of each group

thumbnail Fig. A.1

Top panel: optical spectra of the brightest confirmed member of SL2SJ02140-0535. The main absorption lines used to determine the redshift of the main lens galaxy have been identified. Bottom panel: spatial distribution of galaxies in the group field of SL2SJ02140-0535. Red rectangles show the position of the spectroscopically confirmed members. The dashed magenta circle shows a circular aperture of radius 1 Mpc at z = 0.44. The contours in green show the luminosity contours equal to 3 × 105, 106, 3 × 106 and 107 L kpc-2 from outermost to innermost, as computed by Limousin et al. (2009).
