Table 2.
Average offsets (μ) and maximum errors (m) for different age proxies.
| Errors | Linear | Cubic splines | |
|---|---|---|---|
| τ, τscaled | μ (μHz) | 5.4 × 10−3 | 2.3 × 10−4 |
| m (μHz) | 1.7 × 10−1 | 3.0 × 10−2 | |
| ρc | μ (μHz) | 5.5 × 10−3 | 3.4 × 10−4 |
| m (μHz) | 1.8 × 10−1 | 3.3 × 10−2 | |
Notes. Results from interpolation along the evolutionary track with M = 1.245 M⊙, for all ℓ = 1 mode frequencies, considering the indicated interpolation algorithms. We notice that interpolation errors are the same for τ and τscaled.
