Stellar parameters for samples A and B.

Sample N Teff (1) (K) log g (1) [Fe/H] (1) Var (2) (ppm) Prot (2) (d)
A 686 5000–6000 4.20–4.69 −1.46–0.56 211–39 748 24.0–27.4
B 361 5700–5900 4.21–4.60 −1.08–0.44 211–17 530 15.0–39.8
Sun 1 5778 4.44 0.0 300–1500 27.27 (Sy), 25.38 (Sid)

Notes. Stellar parameters for stellar samples A and B. (1)Effective temperature(Teff), surface gravity (log g), and metallicity ([Fe/H]) values are taken from Huber et al. (2014). (2) Variability range (Var) and rotationperiods (Prot) are taken from McQuillan et al. (2014). We take the solar synodic (Sy) and sidereal (Sid) Carrington rotation period values as a reference.
