Amplitude and offset of the simulated broadband phase curves in the HST, Spitzer, and MIRI-LRS bands. Predictions for the amplitude and offset in Ariel s band is also added to the plots. The black square represents data points from Stevenson et al. (2014) and Morello et al. (2019), or our MIRI-LRS reduction. Each colour is associated with a cloudy or cloud-free scenario. Circles represent the solar metallicity simulations and diamonds the 10× solar metallicity simulations.
