Caption: Figure 9.

HARPS radial velocities of AD Leo between JDs 2453809.7 and 2453871.6 as a function of time (top panel) and folded on the phase of the signal (bottom panel). The black curve denotes the estimated Keplerian curve. The three temporal subsets of data denoted by different colors have been treated as independent data sets with independent nuisance parameters.
