Synthetic Phoenix BT-Settl stellar spectra in the four wavelength regions utilized in the Terrien et al. (2012b) NIR EW metallicity calibration. Spectra are shown for a star with T_eff = 3200 K, log (g) = 5.0, and [Fe/H] = 0.0 with [α/Fe] = 0.0 (maroon, solid lines) and +0.2 (light-blue, dashed lines). These have been degraded to an approximate spectral resolution R ~ 2000. For reference, the same spectra are shown with spectral resolution R ~ 40 000.
