 <p> The fractal structure is as documented in the fractal model. This model could find use for aggregates of coated particles, or aggregates of vesicles.&nbsp;The polydispersity computation of radius and thickness is provided.</p>
 <p style="margin-left: 0.25in;">The returned value is scaled to units of [cm-1sr-1], absolute scale.</p>
