Notes. This table contains an example of the GPS outputs, the compared rotation period values from GLS & ACF, and stellar parameters for 12 randomly selected objects from samples A and B. (1) GPS outcome: in Col. 2, the P_HFIP is given, in Col. 3, its 2-sigma uncertainty, σ P_HFIP, defined from individual inflection points for each Kepler observing quarter. In Cols. 4 and 5, values of α-factor and its 2-sigma uncertainty are reported, respectively. P_rot GPS values in Col. 6, as result of applying Eq. (1) using the factor α = 0.19. (2) Col. 7 shows the P_rot reported by Reinhold & Gizon (2015). (3) P_rot and variability values reported by McQuillan et al. (2014) in Col. 8. (4) Cols. 10, 11 and 12 show the log g, [Fe/H] and T_eff, respectively,taken from Huber et al. (2014). A complete table for the 1047 objects is available at the CDS.
