Dayside and nightside brightness temperatures estimated from the flux ratios using the BT-Settl stellar model spectra by Allard (2013). The shading marks the 68% and 99.7% central posterior intervals, from the darkest to the lightest shade, and the dashed horizontal line shows the best-fitting constant brightness temperature. The previous dayside T_b, estimates for the TESS and Spitzer passbands by Beatty et al. (2019, 2020), and von Essen et al. (2021) are shown as points with errorbars.
