Top: GALFIT best-fit models for A383-LRD1B. For each filter, we show (from top to bottom) the original image, the fitting mask, the best-fit model, and the residual. The overall fits are good, with minimal residuals in most bands. Bottom: stacked residual images for the short-wavelength (SW) and long-wavelength (LW) filters. In both stacks, extended emission (green) is clearly detected with a similar spatial extent. In particular, the SW stack reveals bridgelike emission connecting the red and blue components (indicated by open circles for visualization).
