ATHOS: On-the-fly stellar parameter determination of FGK stars based on flux ratios from optical spectra

1 code implementation5 Sep 2018 Michael Hanke, Camilla Juul Hansen, Andreas Koch, Eva K. Grebel

The analytical relations employing these FRs were trained on 124 real spectra of a benchmark sample that covers a large parameter space of $T_{\rm eff}\approx$ 4000 to 6500 K, [Fe/H] $\approx$ -4. 5 to 0. 3 dex, and $\log{g}\approx$ 1 to 5 dex, which also reflects ATHOS' range of applicability.
