@deepanshs No, no updates. We discussed building a SpinSystemDistribution object to encapsulate all the functions and necessary data to perform LS minimization for some dataset; I currently don't have the bandwidth to work on that feature. Otherwise, I have the necessary fitting functions implemented and workflow outlined in a gallery example.
