Extended Data Fig. 6: One-way transmission through Titan’s atmosphere.
From: The atmosphere of Titan in late northern summer from JWST and Keck observations
Calculations at emission angles θe = 44∘ (left) and at the limb θe = 90∘ (right) for light at different wavelengths probed by JWST NIRCam and Keck NIRC2. JWST filters (wavelengths): F165N (1.65 μm); F187N (1.87 μm); F212N (≃ 2.12 μm). Keck NIRC2 filters (wavelengths): Brγ filter (2.157 μm); H2 1–0 (≃ 2.12 μm). The dots indicate for each filter and viewing orientation the altitude where the effective transmission reaches e−1, and on each curve, the crosses indicate the altitude where the one-way effective transmission reaches 90% (upper cross) and 10% (lower cross). The latter altitude is also used as the threshold altitude of detection.
