Validate new orientation distribution (Trac #1143)

[butlerpd]

The new orientational distribution of oriented particles is complete but needs some validation/testing. The problem is that the current typical way orientational distributions are currently evaluated seems to be through an order parameter defined in the plane of the detector whereas !SasView is trying to go a step (or two) further and bring real physical insights by using the real 3D object and defining an orientational distribution in the frame of the object and then projecting that onto the plane of the detector.

While the output of the code has been looked at by several of the developer group over the past 2 years of development it would be good if there was at least one external expert group that could verify the results are at least consistent with what they do/would expect given the new way of looking at it.

• butler commented:

This is a work in progress with Santa Barbara group but will take much longer for everyone to get on the same page than we can wait for the 4.2 release. Testing so far seems reasonable so moving this to 4.3.

• butler changed milestone from "SasView 4.2.0" to "SasView 4.3.0"
