Notes. Values of observed peak abundance Xpeak are taken from Fig. 12 and represent COM column densities with respect to H2, where we consider H2 column densities derived from either dust (2nd and 6th columns) or C18O 1–0 emission (4th and 8th columns). The modelled peak abundances 
present COM column densities with respect to total H taken from Table 16 from Garrod et al. (2022) multiplied by a factor 2 to roughly convert to abundances with respect to H2. The values in parentheses show the decimal power, where x ± y(z) = (x ± y) × 10z.
