Comparison of photometric variability metrics between the K2P², Harvard (C0–4), and PA (C3–4) pipelines as a function of Kp ( for K2P²). The metrics are depicted by their median magnitude-binned values. (1) Point-to-point median difference variability (MDV). (2) 24-day “long-CDPP” (see Gilliland et al. 2015). (3) 6.5-h CDPP, computed following Gilliland et al. (2011) (see text). Here we have included the lower envelope for the CDPP_6.5h values computed in Gilliland et al. (2011) from nominal Kepler data. (4) Quasi-CDPP_6.5 h as reported by Vanderburg & Johnson (2014) and Aigrain et al. (2015). For the point-to-point MDV and quasi-CDPP_6.5h we have included the median binned values obtained by Aigrain et al. (2015) from engineering data and circular apertures with a 3-pixel radius. (5): Median levels of (unweighted) power spectra from corrected light curves between 260 and 280 μHz.
