Spectra of the H₂O₂ and CO₂ lines calculated with the five thermal profiles described above, for an airmass factor of 1.0 (disk.center), and for a H₂O₂ mixing ratio of 30 ppbv. The color code is the same as for Fig. A.1. Red: nominal model (1); green: Model 2; blue: Model 3; purple: Model 4; light blue: Model 5. The two extreme absorption cases correspond to Model 2 (maximum absorption) and Model 5 (minimum absorption).
