Surface brightness modelling in different filters. Left panels: cut-outs of the HST WFC3 data (left), the imfit model (centre) and the residual (right). Right panels: the same for synthetic JWST NIRCam-like images obtained from the NIRSpec cubes. The black and white extremes in the residual correspond to ±5σ, where σ is the standard deviation of the original image in a background region. We note that there is a small difference in position angle between HST and JWST images (see Fig. 1).
