Ratio between the elevation of the emitting layer ɀ(r) over the expected pressure scale height H_𝑔 for different midplane temperature prescriptions. Left: temperature profile equal to the front layer temperature of each isotopologue. Middle: temperature constant equal to 20 K. Right: temperature follows Eq. (7). The darker and lighter shaded regions represent the 1σ and 3σ uncertainty of each profile, respectively. The gray lines in the top right panel show the ɀ/H ratio from the disks analyzed in Law et al. (2022).
