The first three panels showcase integrated intensity maps (moment-0) for C i (top) and CO (middle) lines, along with their ratio C i/CO (bottom), generated using the radmc-3d radiative transfer code applied to simulation data for the first J-line emission (J = 1–0) at 7 Myr for AGN (left) and NoAGN (right) models. A consistent beam size of 0.06 arcsec × 0.06 arcsec is applied throughout the images, corresponding to a physical scale of 4.2 pc at the comoving radial distance of 14 Mpc for NGC 1068, with a position angle of 0°. Each panel depicts a central 150 pc region of the disc. Overintensity regions in each map are highlighted by contours within the range of their respective colour bars. Concentric circles represent the central 50 and 100 pc radii of the disc.
