Simulated RV as a function of time when the RV effect is due to a combination of inhibition of convective blueshift and a RV photometric effect. The average lifetime of the magnetic regions is 15 days. The rate varies as a A/2(1 + cos 2πt/Pmaɡc) where Pmaɡc = 11 years and A is such that there are on average 50 spots visible each day.
