Redshift distribution of multiple images included in our gold catalogue with known spectroscopic redshift. Images for which the spectroscopic redshift was obtained only by MUSE are shown in grey. Images for which we provided spectroscopic redshifts with JWST are shown in orange. Striped regions represent images with both JWST and MUSE redshift measurements. In the histogram, each multiple image is counted once (i.e. different multiply lensed clumps are not considered separately). The red solid line represents the expected redshift distribution of multiple-image systems, considering the redshift distribution of sources in the field and multiply imaged area in the source plane, which increases with redshift.
