Source plane intensity (left), intensity error maps (middle), and S/N maps (i.e., intensity divided by intensity error, right) for SPT 0125-47 and SPT 2134-50. The gray polygons show the Voronoi mesh used for the pixelized reconstruction and the black line shows the caustic line. Both the intensity and intensity error maps are normalized, where the error maps have been normalized to the maximum of the intensity map, meaning that the value can be seen as a percentage error per pixel. The S/N map provides a measure of the significance of the reconstructed emission.
