^a DACE database https://dace.unige.ch/; ^b Opacities are computed with HELIOS-K https://github.com/exoclime/HELIOS-K (Grimm & Heng 2015; Grimm et al. 2021); ^c We use HITEMP2010 for temperature profiles and UCL-4000 for emission spectra; ^d For ExoMol opacities we make use of the conversion work done by Chubb et al. (2021), which are only used for generating emission spectra. In general, we make heavy use of the DACE (Grimm & Heng 2015; Grimm et al. 2021), ExoMol (Chubb et al. 2021), Kurucz (Kurucz 1992), VALD3 (Ryabchikova et al. 2015) and HITRAN (Gordon et al. 2017) databases.
