Rest-frame X-shooter spectra for image A, image B, and the lensing galaxy. The different arms of the instrument are shown: UVB (green), VIS (blue), and NIR (red). The images are corrected by their respective redshifts (z_s = 0.777 and z_l = 0.230). The atmospheric windows are left blank for the NIR band. The lensing galaxy is uncontaminated by the quasar emission. The wavelength is in the rest frame of the respective object and the position of the emission lines are shown as dashed lines.
