Power law temperature profiles (q = 0.35) as shown in Fig. 4, but now derived from images simulated with the observed uv-coverage (25 minutes integration). Top panel: results for the warm model, that is, the fiducial T13 temperature structure. Bottom panel: results for the hot model, that is, the T13 temperature increased by 30%. The black lines show the midplane temperature profile in the corresponding models used to generate the images. The gray line represents the midplane temperature used by A17. The shaded orange area marks the 1σ uncertainty on the temperature profile derived from the observations (¹³CO, redshifted channel), as shown in Fig. 4.
