Spectral phase curves of WASP-43 b at four given phases, from 0.6 to 12.5 μm, for a super-solar metallicity atmosphere. The black line is the cloudless simulation. Each colour corresponds to a simulation with a different cloud particle size. Each coloured line is a simulation with Mg₂SiO₄ clouds and a different radius. Blue data points and error bars from HST are taken from Table 5 of Stevenson et al. (2017). Spitzer data point are from Morello et al. (2019), and MIRI-LRS data points are from the Eureka! v2 Reduction, as explained above. In each panel, the subplot is a zoomed-in view of the HST data, between 1.1 and 1.7 μm. Dayside corresponds to the planet passing behind its star and nightside to the planet passing in front of its star. The 0.25 phase is the quarter phase between the night and day phases, and the 0.75 phase is the quarter phase between the day and night phases. Thus, the eastern terminator is seen at phase 0.25 and the western terminator at phase 0.75.
