Notes. Details about the observed fields are given in Table 1. Effective temperatures and luminosities are taken from McDonald et al. (2017). The observational durations are listed for all satellites that observed a given star, with the data set used in this study marked in bold face. The column “data points” refers to the number of data points in the reduced and subsequently binned final data set. The column “duty cycle” gives the duty cycle of the binned and gap-filled time series. Stars marked with ( † )are flagged as variable stars in the General Catalogue of Variable Stars (GCVS Samus’ et al. 2017). For ρ Per and ε Mus the catalogue lists a period of 50 and 40 d, respectively. Values for Teff are taken from McDonald et al. (2017).
