Examples for the typical S/N and spectral resolution of the library stars in this paper. Panel a: S/N of the deep spectrum of the G4 subgiant 70 Vir. The larger S/N in the very red wavelengths is mostly due to the larger number of individual spectra. Note that the local peaks in S/N are due to the wavelength overlap of the cross dispersers, which effectively doubles the number of pixels there. Panel b: spectral resolution for the focus achieved for the July 2016 run.
