Rating Curve | Hydrological rating curve. Definition ---------- THIS MODEL IS NOT INTENDED FOR THE ANALYSIS OF SAXS/SANS DATA! This model is in part provided to illustrate the utility of SasView as a fitting program for the analysis of input data that i… |

Pringle-Schmidt Helices | This is the Pringle-Schmidt equation for fitting the helical form factor of an infinitely long helix formed from two helical tapes wrapped around each other at an angle $\epsilon$. The two helices are assumed to have the same width and thickness. Pl… |

Cumulants | The Method of Cumulants. Definition THIS MODEL IS NOT INTENDED FOR THE ANALYSIS OF SAXS/SANS DATA! This model is in part provided to illustrate the utility of SasView as a fitting program for the analysis of input data that is not $I(q)$ … |

Cumulants DLS | DLS analysis by the method of Cumulants. Definition THIS MODEL IS NOT INTENDED FOR THE ANALYSIS OF SAXS/SANS DATA! This model is in part provided to illustrate the utility of SasView as a fitting program for the analysis of input data tha… |

Peak Voigt | This model describes a pseudo-Voigt shaped peak on a flat background. Definition This pseudo-Voigt peak function is a weighted linear summation of Lorentzian (L) and Gaussian (G) peak shapes. The usefulness of this function is that it produces … |

Long Cylinder | Cylinder model for long cylinders. Background The default numerical integration scheme in SasView leads to numerical instabilities in the calculation of the cylinder form factor when the length of the cylinders becomes too long. For practical pu… |

Sphere Concentration A | Spheres with uniform scattering length density reparameterized to used to use the *volume number density* of spheres, NOT the volume fraction of spheres as in the normal SasView sphere model. Also note that, unlike most other SasView models, the … |

Binary Blend | Two-polymer RPA model with a flat background. Definition ------------ This model calculates the scattering from a two polymer blend using the Random Phase Approximation (RPA). This is a revision of the $binary$ $blend$ model posted to the Ma… |

Exponential | Flexible exponential model with a flat background. DEFINITION This model calculates a variety of exponential functions. The scattered intensity $I(q)$ is calculated as $I(q) = \text{scale} \cdot exp(-\text{prefactor} \cdot q^{\text{expo… |

Fractal S(q) | Calculates the structure factor term ONLY from the Fractal model. Definition ------------ The Teixeira & Chen fractal structure factor. Calculates the structure factor for mass fractal aggregates of monodisperse spherical particles of effect… |

Mass Fractal S(q) | Calculates the structure factor term ONLY from the Mass Fractal model. Definition ---------- The Sinha-Mildner-Hall fractal structure factor. The functional form of the structure factor is defined below \begin{equation} S(q) = \frac{… |
