#1206 closed defect (fixed)

Incorrect (and confusing) presentation of dQ from data in instrumental smearing section

Reported by: butler Owned by: GitHub <noreply@…>
Priority: major Milestone: SasView 4.2.1
Component: SasView Keywords:
Cc: Work Package: McSAS Integration Project


Selecting use dQ Data currently displays dQ high and dQ low (for pinhole data at least), However dQ low is not labelled while dQ high is labelled as dQ[%].

Prior to SasView version 4.1.0, the two values were labeled dQ high and dQ low. In 4.1.0 a change was made to the custom pinhole to be useful by asking for a dQ/Q in percent (see #850). The current labels probably were introduced accidentally in that work. However the proper fix should be to change the values presented to be dQ/Q[%] (as one label suggests) and then fix the labels to make it clear what is presented: dQ/Q low[%] and dQ/Q high[%].

From @smk78 in ticket #850

The codebase (see and seems to have some infrastructure for computing %dQ.
I think displaying the %dQ is probably of more use to the user, and we could flag "crazy" values by turning the reporting box(es) red or similar. But exactly what we report probably needs some discussion.

Fix reporting of pinhole resolution on FitPage? when taken from data

GUI now reports dQ/Q as the label suggested. Also labels were fixed to
be more clear. Finally a small bit of code cleanup was attempted. Note
that there is a serious problem with the 2D resolution part of that GUI.
This is a previously unreported problem which may be dealt with in
another ticket or may be done here depending on the effort required.

Fix 2D smearing GUI

Make 2D from data as % of average. Fix input and message boxes to be
the right ones and fix some logic issues

Tested Build#67 on W64 and verify that the GUI now shows dQ/Q in % at Qmin and Qmax.

If one wanted to put a big fat cherry on top of this fix, it would be to make the dQ/Q boxes change colour if the value is 'excessive' in order to draw the users attention to it.
