Model parameter posteriors for increased quality 4 – 18.5 μm Venus-twin spectra (opaque H₂SO₄ clouds). Here, L(·) abbreviates log₁₀(·). Dashed black lines indicate the true values (see Table 1). Solid green area – opaque H₂SO₄ clouds; thin-blue outlined area - transparent H₂SO₄ clouds; orange-hatched area – opaque H₂O clouds; thick-yellow outlined area – cloud-free. Rows (top to bottom) represent different input qualities: R = 50, S/N = 10; R = 100, S/N = 10; R = 50, S/N = 15; R = 100, S/N = 15; R = 50, S/N = 20; R = 100, S/N = 20. Continuation in Fig. D.4.
