Notes. 

(a)

Model names (1st line) include a letter and a number. The letter refers to the initial metallicity, Z (2nd line) and the number to the initial rotation/17O(α,γ) rate used. 0 is for non-rotating models, 1 for models with constant υini/υcrit = 0.4, 3 for increasing υini/υcrit:0.5 − 0.6 with decreasing Z and 2 and 4 for lower 17O(α,γ) rates (CF88/10).

(b)

Model with the 17O(α,γ) reaction rate of CF88 divided by 10.

(c)

in km s-1.

(d)

Since 22Ne is produced and destroyed at the same time in rotating stars, we derived this value from the sum of the 25Mg and 26Mg produced during central He-burning.

(e)

Number of neutron captures per initial seed.
