Reconstruction of simulated strong lensing observation with JWST. Top panels: input source model is depicted next to its reconstruction, which is the mean of the source flux averaged over the approximating posterior. Next, we display the relative uncertainties estimated from posterior samples. Lastly, the residuals between the input and the reconstruction are displayed (described from left to right). Middle panels: simulated JWST data, its reconstruction, relative uncertainty of the reconstruction, and normalized data residuals. Bottom panels: input convergence, its reconstruction, the relative uncertainty of the convergence reconstruction, and the residuals between the input convergence and its reconstruction.
