Table 2.
Estimated systematic offsets for benchmark stars.
| Star type | ΔTeff/K | log g | [Fe/H] |
|---|---|---|---|
| The Sun | −25 ± 4 | −0.070 ± 0.004 | 0.008 ± 0.003 |
| Solar-type | −30 ± 40 | −0.04 ± 0.03 | 0.003 ± 0.004 |
| F dwarfs | 50 ± 40 | 0.08 ± 0.05 | 0.019 ± 0.008 |
| FGK subg. | 0 ± 20 | 0.02 ± 0.03 | −0.03 ± 0.02 |
| Red giants | 50 ± 20 | 0.15 ± 0.01 | −0.07 ± 0.05 |
Notes. We show the best estimates of the systematic offsets (derived − benchmark) and their 1σ uncertainty values in each parameter for each type of benchmark star. We also show this for the Sun alone.
