A diagrammatic representation of data on @S05487@ from large particles, obtained at different angles but at the same concentration, constructed by plotting \(\log _{10}\Delta R\left(\theta \right)\) or \(\log _{10}P\left(\theta \right)\) versus \((\sin \frac{\theta }{2})^{2}\) or \(q^{2}\) and (usually) used for the evaluation of the @R05121@. \(\Delta R(\theta)\) is the @E02236@, \(P\left(\theta \right)\) the @P04429@, \(\theta \) the @S05488@ and \(q\) the length of the @S05494@.
