A 3D rendering of the coronal density and temperatures in the Ω0 and Ω3 models on Day 2. The opaque features display the plasma density. Only the density values of the loops connecting the sunspots are illustrated, by forcing lower values in the coronal volume to be completely transparent. The density features are colored according to their temperature, as indicated by the color bar. The top and bottom rows show an inclined side view and a top-down view, respectively.
