EFOSC2 spectra of the three visible lensed images of PS J2107−1611. The A spectrum is the average of the individual spectra extracted from the two slit angles shown in Fig. 1. Left: complete spectra with fluxes shifted for display purposes. Right: zoom-ins on the Lyα, N V and C IV emission lines. The zoomed-in regions are normalized to their maximum intensity to highlight the larger skewness in these two lines of the A spectrum.
