Gas temperature map 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 (left column) and the grid with H₂O ro-vibrational cooling (right column). Temperature contours of 100 and 300 K are indicated with dashed, black lines. The yellow contours indicate the region in which 90% of the H₂O 11₃₉ − 10₀₁₀ 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).
