MUSE Lyα 2D contours and 1D spectra of the multiple images of families E and F. Left: Contours from a continuum-subtracted narrow band image, centered on the emission line detected at ≈7231 Å, identified as the Lyα emission at z = 4.95. The contours are superimposed on the HST F160W image, to show that continuum counterparts are not detected. Center: Zoom-in of the MUSE 1D spectra of the multiple images E1, E2, E3, E4, and stacked (thicker line), around the detected emission line. Right: Same as in the center for F1, F2, F3, and F4. The spectra were extracted within the orange (E) and brown (F) apertures in Fig. 2, consisting of circular apertures with a radius of 0.8″, and were smoothed with a ∼2.5 Å boxcar filter.
