MACS J0138−2155 as observed through HST and JWST with the following combinations of filters for the color image: F105W+F115W+F125W (blue), F150W+F160W+F200W (green), and F277W+F356W+F444W (red). The positions of the “gold” multiple-image systems are shown with circles. SN Encore is System 1, and SN Requiem is System 2. The foreground (fg) and background (bg) galaxies are marked by cyan diamonds. The dashed squares identify some of the freely optimized cluster members in the lens model, i.e., not constrained by the scaling relations for the cluster members (gray for the ZITRIN-ANALYTIC lens model, maroon for the LENSTOOL I, and that labeled with ID_phot = 116 for the GLEE and ZITRIN-ANALYTIC models). The three jellyfish galaxies are labeled with light-green crosses as JF-1, JF-2, and JF-3.
