Abstract (EN): For the 451 stars of the HARPS high precision program, we study correlations between the radial-velocity (RV) variation and other parameters of the Cross Correlated Function (CCF). After a careful target selection, we found a very good correlation between the slope of the RV-activity index (log(R'(HK))) correlation and the T-eff for dwarf stars. This correlation allow us to correct RV from magnetic cycles given the activity index and the T-eff.
