Notes.

(a)

Logarithm of the maximum He-burning.

(b)

Logarithm of the maximum H-burning.

(c)

Position of maximum energy released by He-burning.

(d)

Degenerate core mass.

(e)

Time between maximum He-burning luminosity and the onset of hydrogen mixing.

(f)

Time between the onset of hydrogen mixing and the splitting of the convective zone.

(g)

Model with Z = 0. All other models, except Z7, have Z = 10-8.

(h)

Model with convective efficiency reduced by an order of magnitude.

(i)

Model that includes overshooting with f = 0.016.

(j)

Model that includes overshooting with f = 0.07.

(k)

Model with initial Z = 10-7.
