Notes. SP-TW, RU-23, and CA-24 refer to the transmission spectra presented in this work, Rustamkulov et al. (2023), and Carter & May et al. (2024), respectively. The reported values for individual parameters are given as a 95% centred credible interval, followed by the median value. The pressure nodes associated with the four temperature values are located at log10(p [bar]) = (1, −3, −7, −9}.
