Notes. For the template stars we adopt the Teff reported in MILES spectral library (Sánchez-Blázquez et al. 2006), except for HD 235299 (Soubiran et al. 2016). The spectral type is derived from this Teff and tabulated values in Pecaut & Mamajek (2013). The best fitting parameters for the sinusoidal function described in Sect. 3.1 are also reported, being t0 = T0(HJD)−2460465.0, and defining
