#659 closed defect (fixed)

check polydispersity distributions

Reported by: pkienzle Owned by: pkienzle
Priority: blocker Milestone: SasView 4.0.0

Cc: Work Package: SasView Bug Fixing

Description (last modified by butler)

Gaussian polydispersity seems to be working, but all others need to be tested. In particular, lognormal weights don't look lognormal.

sascomp gives different answers between sasmodels and sasview 3.x when testing with lognormal, rectangle and schultz distributions.

Users report that the array distribution is not working with sasview 4.0. See ticket #655.

The array issue (#655) was reported by Kriechbaum, Manfred <manfred.kriechbaum@…>

Selecting the option "Polydispersity on / Array" and reading in a 2 column file (representing the size distribution) seems to have no effect on the calculation ("Compute") in version 4.0 (in 3.1.2 it does however).

Make sure project/analysis save/load and copy/paste params work with the different distribution types (array, gaussian, schulz, rectangle, lognormal). Make sure Npts, Nsigmas, min, max and PD are properly preserved.

It is currently failing to load distributions of types other than gaussian.
