Comparison of transmission spectra used in this work. Data associated with the spectrum produced in this work (SP-TW) are shown in black, while data associated with Rustamkulov et al. (2023) (RU-23) and Carter & May et al. (2024) (CA-24) are shown in red and blue, respectively. (a) Transmission spectra, showing wavelength (in μm) on the x-axis and transit depth (in %) on the y-axis. (b) Residual distribution of RU-23 and CA-24, normalised to the transit depth uncertainty of SP-TW. For display purposes, the residuals are binned in steps of 0.5 σ_sp-TW. (c) Empirical cumulative distribution functions (eCDF) for the residuals of RU-23 and CA-24. The values of a one-sample K-S test for a standard normal distribution are given in the legend of the figure. In (b) and (c), the black dashed line represents the PDF and CDF of N(0,1), respectively.
