Notes. The columns provide the adopted EOS, radiative opacity (the heavy element mixture is specified), boundary condition characteristics, superadiabatic convection treatment, nuclear cross-sections and initial deuterium abundance. All these codes use a solar-calibrated convection efficiency, except DVD09.

^(a)

BCAH98 models have been computed also for α = 1; we used this latter value of α for the comparisons of 0.4 M_⊙.

^(b)

DVD09 adopt the Allard et al. (1997) atmospheric models for M ≤ 0.6 M_⊙ and the Heiter et al. (2002) ones for M > 0.6 M_⊙.

^(c)

DVD09 models were computed adopting the MLT formalism for M ≤ 0.6 M_⊙ and the FST for M > 0.6 M_⊙.
