Final MUSE spectra of the double lensed AGN systems, with target names and redshifts indicated in each panel. The spectra were extracted from the circular apertures shown in the white-light images of Fig. 2 (same color-coding), corrected for Galactic extinction, normalized to Gaia magnitudes, and shifted to the rest frame. Vertical dotted purple lines mark the expected positions of prominent emission lines at the redshift of AGN A. The gap around λ_obs = 6000 Å corresponds to the NGC used in AO observations.
