Description
It would be useful in some circumstances for the fitting engine to have access to data operation parameters, so that examples such as the following can be fit:
S(Q; p) = scale * (Ia(Q)-BKGa)/ (Ib(Q)-BKGb) + Bkg
with parameters p from the structure factor S as well as scale BGKa, BKGb and Bkg.
See the discussion on ticket #1157 for more details.
Note: See
TracTickets for help on using
tickets.
This fit requires two datasets and one model, which sasview does not support. You could change the data class so that it has fittable parameters, and have these parameters created automatically as part of the data operations menu.
Need to update the gui so that the fit panel presents these parameters to the user along with the model parameters.
Need to update the saved project file so that the original data sets and the operations are stored.
Similar work needs to be done for multiple scattering (#1067).
