The particle radius *R*451 represents the radius of the particle where the scattering length density profile decreased to 1/2 of the core452 density. The |sigma| :sub:`fuzzy`\ is the width of the smeared particle surface; i.e., the standard deviation453 from the average height of the fuzzy interface. The inner regions of the microgel that display a higher density454 are described by the radial box profile extending to a radius of approximately *Rbox* ~ *R* - 2\ |sigma|\ . The455 profile approaches zero as *Rsans* ~ *R* + 2\ |sigma|\ .451 The "fuzziness" of the interface is defined by the parameter |sigma| :sub:`fuzzy`\ .
