Pixelized source plane models for the red and blue bins for SPT 0125-47, as described in Section 4.2.2 with source plane intensity (left), intensity error maps (middle), and S/N maps (i.e., intensity divided by intensity error, right). 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.
