Integrated fluxes of several H₂O (left panel), ¹²CO₂, and ¹³CO₂ (middle and right panels) line complexes plotted as a function of cavity size for grid with H₂O ro-vibrational cooling. Properties of these line complexes can be found in Table 2. Nominal H₂O and CO₂ midplane snowlines in the full disk model are indicated with colored bars. Data points are connected by dashed lines if the line flux drops below 10⁻¹⁵ erg s⁻¹ cm⁻², indicating that the lines will become more difficult to observe.
