VizieR Online Data Catalog: Spectroscopic analysis of CKS. II. Metallicities (Ghezzi+, 2021)
Abstract
The sample and data analyzed in this work are the same as in Paper I (Martinez+, 2019, J/ApJ/875/29). The California-Kepler Survey (CKS) team obtained high-resolution spectra for the target stars with the High Resolution Echelle Spectrometer (HIRES) spectrograph on the Keck I 10m telescope (Maunakea, Hawaii). We analyzed their reduced spectra, which are publicly available. The resolution of the HIRES spectra analyzed is R~60000, and the wavelength coverage is almost complete in the interval 3640Å-7990Å. The signal-to-noise ratios (S/Ns) per resolution element of the spectra for targets in our complete sample range from ~10 to ~300, with a median value of ~60.
