Reply to Comment on "Influence of Noise on Force Measurements" [1012.5371]

Having a priori knowledge of the force acting on a noisy system it is possible to solve the issue relative to the interpretation of multiplicative noise terms (aka Ito-Stratonovich dilemma). We experimentally show that for a Brownian particle the anti-Ito convention is correct. This permits us to reconcile force measurements based on the equilibrium distribution and on the drift velocity of a Brownian particle in a diffusion gradient.
