A comparison between X-shooter spectra and PHOENIX models across the HR-diagram

Open Access

Table F.1

Fractions of spectra that prefer [α/Fe] = +0.4, for metal-poor and metal-rich stars.

Wavelength
range	[Fe/H] < −0.5	[Fe/H] ≥−0.5
UVB	90%	70%
VIS	90%	46%
NIR	50%	35%
ALL	35%	42%

Notes. Fits are done at R = 3000, using the inverse-variance weighted χ².
