The weight equation in Sect. 3.1 of Mossoux et al. (2015) unfortunately features a typo. The correct equation should read: (1)with CRsrc + bkg the count rate of the Bayesian block of the source+background event list and CRbkg the count rate of the corresponding Bayesian block of the background that is surface-corrected. As introduced in the first preprint version of the proceeding of Scargle et al. (2013), this weight equation adjusts the Voronoi time-interval in order to subtract the average background. The results presented in Mossoux et al. (2015) remain unchanged since they were all obtained following the recipe of Scargle et al. (2013) and using the correct equation for the Voronoi time-interval weighting.

Therefore, the “alternative” photon-weighting recently tested by Worpel & Schwope (2015) in their Sect. 4.6 (w ≡ 1 − CRbkg/CRsrc + bkg) is actually equivalent to the recipe of Scargle et al. (2013) that we used in Mossoux et al. (2015) since the photon-weighting is equal to the inverse of the Voronoi time-interval weighting. Indeed, the “alternative” photon-weighting of Worpel & Schwope (2015) is identical to those used in Eq. (1) of Mossoux et al. (2015) to compute smoothed light-curve.
