Multi-wavelength source reconstruction of H1429−0028: CO (J:4 → 3) (uniform weight, top row); 7-GHz continuum (Briggs weight, robust = 5, top middle row); 234-GHz continuum (uniform weight, middle row); K_s-band (bottom middle row); and F110W-band (bottom row). Left column shows the observation data, while the second column shows the model image-plane. The third column shows the residuals with a scale range from −4σ to 4σ. Contours show −3σ (solid white), −1σ (dotted white), 1σ (dotted black), and 3σ (solid black) levels. The fourth column shows the source-plane reconstruction, with the caustic overlaid, and the physical scale given by the errorbar. The K_s-band frames have a slight tilt shown by the two arrows in the left column.
