ACS image reconstruction of the most probable model with a source grid of 64 × 64 pixels. Top left: observed ACS F814W image. Top middle: predicted lensed image of the background AGN host galaxy. Top right: predicted light of the lensed AGNs and the lens galaxies. Bottom left: predicted image from all components, which is a sum of the top-middle and top-right panels. Bottom middle: image residual, normalized by the estimated 1σ uncertainty of each pixel. Bottom right: the reconstructed host galaxy of the AGN in the source plane. Our lens model reproduces the global features of the data.
