Phoretic contribution to tracer motion. Comparison of the radially averaged velocities of tracer particles as a function of radial distance from the centre of a stuck symmetrically Pt-coated colloid in water, and in 10% H2O2. The solid lines are adjacent averages with a window of 5 points to aid the eye
