Notes. FAP = E/G (excellent/good) as defined by Baliunas et al. (1995). MS = main-sequence star, G = giant. Pcyc is given with its standard deviation; thus there are no ‘error bars’ for stars with only one detected cycle. γ for the Sun was calculated from solar cycles 21–23, for which MW+SP data are available, but to calculate ⟨tr⟩/⟨td⟩, cycles 1–20 were also included, where all tmin and tmax are from the dates listed in Hathaway (2015). Source of Teff for the Sun: Cox (2000).
