For example, to fit the volume fraction of an sld mixture where the volume fraction is the same across the entire series, but the slds of the mixture components are different across the series, you want to define a parameter Vf and set: {{{ M1.sld = Vf*A1 + (1-Vf)*B1 M2.sld = Vf*A2 + (1-Vf)*B2 ... }}} where A1, B1, A2, B2, ... are known values. You then want to set limits on Vf to (0,1) and set it as a fitting parameter.",defect,new,major,SasView 5.1.0,SasView,,,,SasView GUI Enhancements
