RV shifts produced by a single spot at θ = 90° with a size of A_Sn = 1.6 × 10^-3 stellar surfaces on a Sun-like star with i_∗ = 90° for a simulation without (Q = 0, in red) and with faculae (Q = 3.0, in blue). The result of simulating a rotating star (P_rot = 25 days) without convection is plotted with a dashed line, showing the flux effect. The simulation of a convective star without Doppler shifts is plotted with a dotted line. Both effects are included in the results plotted with a solid line. The HARPS passband is used to compute all the RVs.
