Fig. 2
Bθ(λ) sensitivity: number of extrema above 2σ in ~ 200 Å bins against wavelength for four sets of stellar parameters: the Sun; Teff = 6000 K, log g = 2, [M/H] = 0.0; Arcturus; and Teff = 4500 K, log g = 4, [M/H] = −0.5. The Bθ(λ) vectors from left to right are: θ = Teff, log g and [M/H]. The grey stripes represent the final wavelength regions selected for the AMBRE:FEROS analysis (see Table 2).
