Indirect Geometry Changes¶
A new algorithm IndirectILLReductionDIFF added for treatment of diffraction detector data from the indirect geometry beamline IN16B at the ILL.
Three fitting functions IsoRotDiff, DiffSphere and DiffRotDiscreteCircle have been made available in the fitting browser
IsoRotDiff, DiffSphere and DiffRotDiscreteCircle have been added to the function options in Indirect Data Analysis ConvFit.
The Abins Algorithm has an additional “setting” option which may be used to select between configurations of a given instrument. (For TOSCA this is a choice of forward/back detector banks, for Lagrange this is a choice between monochromator crystals.)
Support has been added to Abins for the ILL-Lagrange instrument. As Lagrange collects inelastically scattered neutrons over a wide solid angle, the spectrum is computed at several angles and averaged. Resolution functions are applied depending on the monochromator setting.
In Indirect Data Analysis F(Q) fit the default fitting function remains None when switching to EISF.
Added a scroll bar to the Bayes interface tabs and Elwin and I(Q, t) in data analysis for users on small screens.
IN16B’s single detectors are now correctly taken into account when computing the energy transfer in IndirectILLEnergyTransfer.
Detector tables produced from _red and _sqw workspaces now use Q elastic as the label for its column instead of Q.
The x range markers on the Symmetrise plot of Data Reduction are no longer restricted in movement.
The x range markers on the ISISDiagnostics plot of Data Reduction remain present.
Fixed a crash on the Data Analysis interface when attempting to drag the Start and End X sliders on the preview plot.
In IsoRotDiff, DiffSphere, and DiffRotDiscreteCircle Aliases have been removed to avoid clashes with interfaces.
Stopped error warning thrown when adding EISF data to F(q) fit if Width has already been added.
Fixed a bug that caused the spectra list in F(q) fit to be blank when reopening the add workspace dialog.
Previous fits in the Indirect Data Analysis fit tabs no longer erased when changing to the full function view.
Fit ranges in Indirect Data Analysis can now be negative.
