#791 new enhancement

make fractal a structure factor model

Reported by: pkienzle Owned by:
Priority: major Milestone: SasView 4.3.0
Component: sasmodels Keywords:
Cc: Work Package: SasModels New Model


Currently fractal and core_shell_fractal are implemented as P(q) * S(q), where P(q) is the sphere structure factor for fractal or the core shell sphere for core_shell_fractal and S(q) is the fractal structure factor.

Propose splitting the S(q) into its own structure factor model so that all variants of fractal clustering are supported at once.

This can be done in two pieces — treating the model as such in the background allows for cleaner reuse of code. PK says this has been done in his branch and should be implemented in 4.1. The second part is to present this to the user as independent structure factor. This may well be a good idea, but there is concern about how to distinguish different approaches to the fractal Sq and how users will know what to do. This requires some thinking and discussion before implementing so moving this to 4.2 for now
