Standardized Lomb–Scargle periodogram of the a CenB RV residuals. The noise model ℳ_d used to create these residuals is taken from Dumusque et al. (2012). p-values estimated by a classical bootstrap procedure (see text) are shown with the dashed lines. Mean p-values derived with algorithm 2 are shown with solid lines, and their credibility interval with the shaded regions. The peak at 3.2 days is shown by the gray vertical arrow.
