The pure form factor models have been converted to the new Fq API so they now support beta approximation.
comment:4 Changed 5 years ago by grethevj
I am introducing F1 and F2 for the following models:
raspberry (plus checking the normalization of the model and fixing if needed)
polymer micelle
I am looking into the possibility of doing the same for the following models:
pringle
linear pearls
pearl necklace
stacked discs

- Component changed from SasView to sasmodels
- Milestone changed from SasView Next Release +1 to sasmodels 1.0
Some of personal thoughts for discussions.
Among the initial list of form factors provided by Paul Kienzle, here is my tenative priority list. This list will change for sure based on the progress of the project. But for now, these are my initial thoughts.
Please feel free to add/review/modify the list. (Here, only the form factor models are considered. GUI for the beta approximation and effective radius for S(Q) may be discussed in a different ticket.)
1) High priority:
Orientation average ( <F> )
Ellipsoid
Cylinder
Size polydispersity
Sphere
ellipsoid
cylinder
vescile
2) Medium priority
Orientation average:
core_shell_cylinder
Combining the orientation average and size average
ellipsoid
cylinder
core_shell_cylinder
3) Models without beta approximation ( Form factor models can not be easily implemented to calculate <F>.)
In general, models in this list will not be considered to have the beta approximation.
