Time series of the 182 RVs obtained for 7 CMa from September 2000 to April 2019 with Lick (blue), UCLES (orange), HARPS (before/after the fiber upgrade of 2015 in green/purple, respectively), and SONG (red) facilities. The vertical gray lines indicate the error bars including jitter. The best double Keplerian fit to the data is drawn with a dotted line, while the solid black line indicates the best dynamical two-planet fit. The residuals of the dynamical fit and the difference between the Keplerian and dynamical models (solid gray line) are shown in the bottom panel.
