Standard In the stellar evolution calculations, the boundary of convective zones is determined using the canonical Schwarzschild's criterion.

Overshooting In this case a mixed zone is added beyond the Schwarzschild boundary. This is the overshooting zone. The existence of such a zone is still a subject od debate (see the literature) but this hypothesis is supported by several observational evidence.

Standard and non-standard models have been computed with a scaled-solar mixture and an alpha-enhanced mixture. For each of the two mixtures, models with two values of the Reimers mass loss parameter are available (eta=0.2 and 0.4).
