Proposed C/O diagnostics: integrated flux ratios H2O/C2H2 vs. CO2/H2O (left) and CO2/C2H2 vs. CO2/H2O (right). The colors of the scatter points indicate the C/O ratio (see Fig.6). C/O ratio contours are shown as black lines, O/H contours as cyan lines, and C/H contours as red lines. The grey stars indicate the observations. The observed fluxes are taken from Gasman et al. (2025).
