Synthetic ALMA observation of the 220 GHz continuum in our nominal simulation with thermal noise, but without u v-plane filtering. The inset is centered on the circumplanetary environment, which is barely recognizable (at 8 σ, but confused with structures along the planetary wake). A beam ellipse is shown in the bottom left corner and also in the inset. The contour levels in the inset start at 3 σ and then rise by one σ in alternating colors. The color stretch in the figure and the grayscale in the inset are linear and cover the full range of intensities. The tick marks in the inset are placed at 0.3^′′ intervals.
