Summary of the empirical and diffusion model results.

| Feuchtgruber | 7.2 × 10-9 | 7.1 × 10-9 | |
| Orton | 9.3 × 10-9 | 9.0 × 10-9 | |

| Diffusion model | |||
|
|

| Thermal profile | Internal source | External source | |
| yCO | φCO | y0 | |

| Feuchtgruber | 1.9 × 10-8 | 2.2 × 105 | 3.1 × 10-7 |
| Orton | 2.7 × 10-8 | 2.7 × 105 | 3.9 × 10-7 |
Notes. All results are mole fractions, except φCO (in cm-2 s-1). The cut-off level in the “stratospheric” empirical model is at 100 mbar. The internal source value of yCO in the diffusion model enables fitting the CO line core amplitude, but the line is too broad and additional broad wings incompatible with the data are generated.
