Line ratios for 12CO. The emission was convolved with a 0.07′′ resolution beam for sources located at a distance of 150 pc. The vertical black dashed line indicates the radial location of the planet. The CO J = 6-5/2-1 line ratios shows the effects of the varying gas temperature much more clearly than the CO J = 3-2/2-1 line ratios.
