It is much more accurate in single precision. This affects many models, including sphere and ellipsoid models. The cylinder models are using J1(qr)/qr, which has its own numerical expansion and does not suffer from this problem. Should probably settle on one or the other and move it into the library. So even though the double precision values for sphere, ellipsoid and triaxial ellipsoid differ by more than 5e-14, they are still marked good. Similarly, the Teubner-Strey model checks out against the quad precision version and so is marked good. 104 104 105 ^**^some models such as binary hard sphere and raspberry are inherently "unstable" in certain regions of parameter space. They require double precision but the difference between old !SasView and sasmodels is still higher than nominally allowed. However hard to say which is more correct at this point.105 OK. some models such as binary hard sphere and raspberry are inherently "unstable" in certain regions of parameter space.

However hard to say which is more correct at this point. 106 106 107 107 List of standard parameters has moved to the instructions page
