Effect of the immobile subtraction algorithm. A) Molecules are diffusing and binding to fixed locations. B) The RICS function is the sum of the diffusion and the binding. When the molecules are bound they give a contribution to the RICS function which is due to the shape of the PSF. C) Since the location of binding are fixed, this contribution can be subtracted using the immobile subtraction algorithm.
