Periodogram of (top panel) the radial velocities calculated with template-matching for Gl96 from the SOPHIE+ measurements, corrected from the zero-point drift; (middle panel) the time series of the master correction for the zero-point drift applied; (bottom panel) the uncorrected radial velocities for Gl96 (prior to the application of the master correction). The horizontal lines correspond to 50%, 10%, and 1% FAP, respectively.
