Notes. The surface rotation periods, Prot, were measured by García et al. (2014) from the Kepler observations. The columns ΔT and Nspec corresponds respectively to the interval of time covered by the Hermes observations and the associated number of analyzed spectra. The two stars indicated by the symbol (†) a re candidates for hosting a planetary system from the Kepler Objects of Interest (KOI) list (source: MAST at https://archive.stsci.edu/kepler/).

(a)

In the case of KIC 7296438, three Hermes spectra were collected, but only one spectrum has a signal-to-noise (S/N) high enough to measure the index.
