Top: TRES and APF radial velocity measurements. Bottom: TRES and APF radial velocity measurements phase-folded to the period determined by the global fit (P = 2.25477 days). Black points represent the APF radial velocities and their uncertainties. Green dots represent the TRES radial velocities and their uncertainties. The red line represents the global fit to the system determined in Section 4.1. The bottom panels show the residuals of the global fit.
