Zoomed-in view of CO₂ spectra of the disk radiative transfer model with M15 ice mantle composition and MRN size distribution, a_max = 0.25 µm (model #4); τ₁, a_max = 1 µm (model #5); τ₃, a_max = 3 µm (model #6); τ₅, a_max = 5 µm (model #7); as observed at different disk inclinations. Top panels: flux spectra normalised at 4.1 µm. Middle panels: linear baseline corrected spectra with baseline reference points taken at 4.1 and 4.45 µm. Lower panels: evolution of the optical depth in the core (4.27 µm), the blue wing (4.22 µm), and red wing (4.31 µm) with disk inclination.
