Abundance maps of H₂O (first and second columns) and CO₂ (third and fourth columns) for the models with no cavity (top row), a 1 AU cavity (middle row), and a 5 AU cavity (bottom row) for the fiducial grid without H₂O ro-vibrational cooling (first and third columns) and the grid with H₂O ro-vibrational cooling (second and fourth columns). The H₂O and CO₂ snowlines (defined as n_gas/n_ice = 1) are indicated with solid light blue and pink lines, respectively. The dashed, dark blue line shows the dust τ = 1 surface at 15 µm. The yellow contours indicate the region in which 90% of the H₂O 11_3,9 − 10_0,10 line emission at 17.22 µm (E_up = 2438 K) originates. The red contours indicate the origin of 90% of the CO₂ 01¹0 − 00⁰0 Q(20) line emission (E_up = 1196 K).
