Solar System tests disfavor f(R) gravities

Abstract
Using the elegant method employed recently by Erickcek, Smith and Kamionkowski, on the premise that the space-time of Solar System is described by a metric with constant-curvature background added by a static perturbation, we show that many f(R) gravities are ruled out by Solar System tests.
