Notes. The presented values are obtained from the specified work (to the authors best knowledge) at 300 days unless specified otherwise, if the data was available.

(a)

Extracted from plot.

(b)

Results from three models; standard, and two different He destruction rates, respectively.

(c)

Result from mixed model, unmixed model, and a semi-mixed model made to fit observations.

(d)

Several models are investigated in this work, however the 15 M⊙ model is shown here as this is the most in-depth discussed.

(e)

This model have two zones significantly contributing to CO production; 4A – O/C zone and 4B – He/O/C zone.
