Notes. These include clear or hazy atmospheres with scaled solar metallicities. We adopted the formalisms of Lee et al. (2013) for the hazy models, where α denotes the particle size in µm, the mixing ratio is χc = 10−12, and the extinction coefficient is Q0 = 40. Lines in bold correspond to the synthetic spectra shown in Fig. 7. Nominal wavelength ranges of (a)HST WFC3-G141 scanning mode, (b)JWST NIRISS-SOSS mode, (c)JWST NIRSpec-G395M mode, and (d)JWST MIRI-LRS mode.
