Eclipse depths in ppm as a function of the internal temperature T_int and the parameter E_* based on the HELIOS model calculations described in Sect. 6.4. The six panels show the eclipse depths in the various passbands. White, solid lines depict the measured occultation depths from Table 4, dashed lines refer to their 1σ error bars. The red lines for the two Spitzer passbands refer to the eclipse depths reported by Beatty et al. (2019).
