Group members (squares) identified as those galaxies whose redshift is within 0.581 ± 0.011, equivalent to the mean redshift of the group with a spread of 2000 km s⁻¹ (rest-frame). The colored regions represent the apertures within which we extracted the spectra of the multiple images of A and B (blue), C (green), D (purple), E (orange), and F (brown). The spectra of E and F, which do not present an HST-detected continuum, are extracted within circular apertures with a radius of 0.8″. The dashed gray curve shows a circle with a radius of 50 kpc, which represents approximately the average Einstein radius of the system.
