Conservative detection limits on msini for time-series with more than four measurements. Planets above the limit are excluded, with a 99% confidence level, for all 12 trial phases. Some panels appear with two curves: the upper one is the detection limits before any model is subtracted and the bottom one is for the residuals around a chosen model (composed of planets, linear drifts, and/or a simple sine function). See Sect. 6 for details.
