Abstract
With the aim of using classic spectroscopic methods with high resolution and high signal-to-noise ratio in the NIR spectral window, we made a selection of 66 FGK-type stars observed with CARMENES, the brand-new, ultra-stable, double-channel spectrograph at the Spanish-German 3.5m Calar Alto telescope. These spectra are part of a CARMENES stellar library. We applied the equivalent width method to derive the spectroscopic stellar parameters (T_{eff}, log{g}, {ξ}_{micro}, and [Fe/H]) using the StePar code along with four new iron line lists covering the whole CARMENES spectral range (550 - 1700 nm).
