The RV time series used in the LTT 3780 RV modeling. Each set of three rows shows the RV time series for a given instrument. The top row shows the mean-subtracted RV-time series for each instrument, with the maximum a-posteriori RV model shown in black, while the middle row shows just the stellar activity component of the RV time series, with the corresponding best-fit stellar activity signal shown in black. The residuals between the best-fit model and each time series are shown in the bottom row.
