One-dimensional MUSE spectrum (blue) for the 182 multiple images used to build the lens model. Spectra are centered over the two most relevant atomic transitions: Lyα or C III]λλ1907, 1909, depending on redshift. The orange line is the error spectrum, and the red vertical line at the center of each cutout marks the wavelength of Lyα (or C III]λ1907) at the given redshift. The spectra have been extracted from circular apertures with diameter. Each thumbnail reports in the top, from left to right, the ID, redshift and the line transition. In each cutout, the inset on the top-left shows the HST RGB image corresponding to red = F814W, green = F606W, blue = F435W bands if z <  5.2, or red = F105W, green = F814W, blue = F606W bands if z >  5.2. The inset on the top-right is the continuum subtracted MUSE image of the same object, collapsed along the wavelength direction over 10(20) Å for C III (Lyα) line.
