Atmospheric parameters chosen to generate our reference synthetic spectra.
| Star | Model | Teff | log g | [Fe/H] | [α/Fe] | ξt |
|---|---|---|---|---|---|---|
| α Cen B | MARCS | 5250 | 4.5 | 0.25 | 0 | 1 |
| Sun | ATLAS | 5800 | 4.5 | 0 | 0 | 2 |
Notes. Spectra were generated either by a MARCS or ATLAS model specifying an effective temperature Teff in K, a surface gravity log g, a metalicity [Fe/H], and [α/Fe] value and a micro-turbulence velocity ξt in km s−1.
