Relative abundance comparison across each of the three transits, for the morning limb. The stellar values from Tabernero et al. (2021) are shown as a vertical grey line, with their 1σ contours shaded where measured. The solar values from Asplund et al. (2009) are shown as a vertical orange line, with their 1σ contours shaded. The weighted mean of the retrieved relative abundances in regions C and D (morning) from G2023 are also shown, where measured. Otherwise, the relative abundances measured for the whole terminator from P2023 are shown.
