¹²CO (2–1) integrated intensity map of the observational data (top left) compared to the synthetic maps built from the simulations reƒ (top middle), e05 (top right), i30 (bottom left), i60 (bottom middle), and ei60 (bottom right). The discs were rotated back in the observed disc plane to allow for a proper comparison to the observations. The beam sizes are plotted in the bottom left corners.
