Results of the juliet joint fit to the PFS RVs. Top: PFS RVs over time (black points) and full best-fit juliet model (gray curve). Middle: phase-folded RV measurements from PFS. The black curve is the best-fit juliet RV model, the gray points are the unbinned RVs, and the red diamonds are the RV measurements binned in 0.05 units of orbital phase. Error bars are the quadrature sum of the PFS internal uncertainties and the RV jitter estimate from the juliet fit. The best-fit RV semiamplitude is ﹩K={10.95}_{-1.43}^{+1.50}\,{\rm{m}}\,{{\rm{s}}}^{-1}﹩. Bottom: RV residuals after the data have been subtracted from the best-fit model.
