Transmission spectra obtained for the different PAMPRE and COSmIC haze analogs from near-IR to far-IR. The data are analyzed using the iterative model with an SSKK loop to ensure a physical correlation between n and k. The first step presents a simulation considering the film thickness and a real refractive index constant in the entire IR range (black curve). The second step accounts for variations in n in the IR after calculation with the SSKK model (orange curve). The final step presents the complete fit to the data with n and k correlated by the SSKK model (red curve).
