WASP-43b model phase curves at selected wavelengths, where the spectrum is dominated by H₂O (1.4 μm), CH₄ (3.3 μm), by no particular molecule (4.15 μm), and CO/CO₂ (4.5 μm). The longitudinally resolved data set matches the phase curve much better than the disk-integrated data set when local properties are assumed in each phase. However, the spectral mapping is not perfect, in particular, it does not perform well at first and third quadrature. This is consistent with these phases being the most problematic for the atmospheric retrievals.
