Color-composite RGB image of A2744 (credits: https://esahubble.org/images/heic1401a/). Circles show the positions of the 90 spectroscopically confirmed multiple images included in the SL model, color-coded according to their redshift value. The size of the circle illustrates the adopted (rescaled) positional error in the modeling. Colored squares highlight the systems of multiple images for which additional lensed clumps have been identified. The two BCGs (BCG-N and BCG-S) are labeled in gray.
