If you create a model data set in Igor using the Uniform_Ellipsoid model then recreate the model in sasview using the EllipsoidModel, and using a custom slit smear in sasview of 0.117 the two models do not line up. I believe this is something in sasview and the way it calculates smearing. This was something I found while at NIST and think I told you about, however getting Bumps running was more of a focus at the time. I wanted to make sure this was documented and you knew about it. I have attached a test data set from Igor using the following parameters background: 0 radius_a: 500 radius_b: 15000 scale: 0.05 sldEll: 1e-6 sldSolv: 6e-6 I also attach a pdf of the plot from sasview of the comparison between the two data sets.
