Pilot-survey spectra for the dwarf-star sample observed with VATT and PEPSI at R ≈200 000. The respective x-axes are wavelength in Angstroem. Panel a shows the available wavelength coverage with cross dispersers III (4800–5440 Å), V (6280–7410 Å), and VI (7410–9120 Å). Panel b shows sample stars for a wavelength window around the Li I 6707.8-Å line. Panel c shows the same stars but for a wavelength window around the core of the chromospheric Ca II IRT λ18498-Å line. We note that all stars with lines shifted with respect to the laboratory wavelength appear to be spectroscopic binaries. We also note the large line broadening for some of the targets.
