Table 6

Predicted uncertainties on the parameters ϵ(x).

Xc ϵ(ℳ) ϵ(α) ϵ(Z/X0) ϵ(τ)

0.6 2.53 9.65 19.63 18.49
0.4 2.36 8.16 18.09 11.78
0.2 2.31 6.87 16.77 11.82

Notes. ϵ(x) are given for a 0.9 M star. The set of observables is the same as that for Table 4. The combination of the parameters is P = (ℳ,α,Z/X0). The relative error on the initial metallicity parameter is σ(Z/X ∗ )/(Z/X ∗ ) = 23%. The uncertainties on the metallicity parameter ϵ(Z/X0) are shown in red.
