Points represent the values for the long-term RV slopes fitted on Lick and HARPS-N data. The red square is the value for the first Lick setup with large error bars, which was not taken in consideration when we fit the planetary parameters. The black dotted-dashed line represents the fitted orbit of the binary companion from the two-objects fit of Table 5. The blue dashed line is the long-term slope for the best-fit orbit for the stellar companion reported by Drummond (2014), assuming a mass value of 0.4 M_⊙.
