Top: 19×11 arcsec² cutout of an RGB image based on F277W, F410M, and F444W centered around coordinates α= 2:40:02.338, δ = −1:37:15.297. The yellow square encloses the region that contains our galaxies; its dimensions are 2.8 × 2.4 arcsec². The four multiple images of the z ∼ 7 background source are highlighted with green circles and labeled with the IDs listed in Table A.2. The green colors highlight this source’s F410M excess; we also noticed F410M excess in our galaxy sample, suggesting they are at similar redshifts. Bottom: 4×3 arcsec² cutout of the same RGB image around our sample, with the scale saturated to also show SAT1 and SAT2. The source-plane positions of the sources after the lensing correction are depicted as crosses (yellow for the LRDs and green for the satellites).
