Add a model here when you are working on it. Mark it as converted when it is tested and pushed.

The err columns are the result of running multi_compare.sh, which generates random parameters for comparison against sasview. double should be at most 5e-14 relative error, single should be 5e-5.

./multi_compare.sh all 200 1d200 mono double ./multi_compare.sh all 200 1d200 mono single

Some models still have issues when run using single precision (lamellarPC for example).

We are not dealing with magnetism at this point as it requires some work on the wrapper functionality. Thus the *Magnetic* column below is for reference as to which models need attention. The *SESANS* column should be used to indicate if the model is a priority (1 highest, 4 lowest).

^{*} using taylor expansion near 0 for fq = 3 (sin(qr)/qr - cos(qr))/qr^{2}; using quad precision as a cross check, this is more accurate than computing the direct expression for qr < 0.1 in double precision, and so the values will differ from those in sasview. 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.

1GList of standard parameters (name = meaning):

- radius = radius
- sld = scattering length density of particle
- solvent_sld = scattering length density of matrix
- cor_length = correlation length
- exp = exponent (example: porod_exp)
- peak_pos = q_peak or q0 etc
- theta, phi, psi
