+Small angle X-ray and Neutron (SAXS and SANS) scattering examines the
+scattering patterns produced by a beam travelling through the sample
+and scattering at low angles.  The scattering is computed as a function
+of $q_x$ and $q_y$, which for a given beam wavelength corresponds to
+particular scattering angles. Each pixel on the detector corresponds to
+a different scattering angle. If the sample is unoriented, the scattering
+pattern will appear as rings on the detector.  In this case, a circular
+average can be taken with 1-dimension data at $q = \surd (q_x^2 + q_y^2)$
+compared to the orientationally averaged SAS scattering pattern.
 
 Models have certain features in common.
