Comparison between the uncertainty estimates based on a synthetic spectrum.
| Parameter | σmc | σfit | σsme | σdelta |
|---|---|---|---|---|
| Teff [K] | 10.2 | 14.5 | 54 | 121 |
| log g [log (cm s−2)] | 0.020 | 0.027 | 0.28 | 0.16 |
| [M/H] dex | 0.0065 | 0.0081 | 0.04 | 0.07 |
Notes. σmc is based on the distribution of a Monte Carlo simulation, σfit is based on the covariance matrix of the least-squares fit, σsme is based on the method described in Sect. 2.7, and σdelta is based on the scatter of the derived values compared to the reference values from other studies in Sect. 6.
