Comparison between different emission spectrum models. The shaded areas show the 68%, 95%, and 99.7% central posterior intervals for the eclipse depths as estimated from the joint modelling, and the black points show the passband-integrated emission spectrum models. Helios-r2 corresponds to the model presented here, VE21a and VE21b to the models in von Essen et al. (2021), BT-CN, BT-DS, BT-NG, and BT-ST to the best-fitting BT-Cond, BT-Dusty, BT-NextGen, and BT-Settl models by Allard (2013), respectively, and DRIFT-PH to the best-fitting Drift-PHOENIX model (Witte et al. 2011).
