Indirect Geometry Changes¶
New Features¶
In the Fitting tabs in Inelastic Data analysis the button for fitting the currently plotted spectra has been renamed and rescaled to fit the interface.
An option has been added to ISIS Energy Transfer that will group outputs by the position of the sample changer using GroupBySampleChangerPosition .
Bugfixes¶
A bug has been fixed in the
CASTEP .phonon
file import for the Density Of States interface and SimulatedDensityOfStates algorithm. The bug was causing some q-points to be misidentified as duplicate Gamma-points and removed.A bug has been fixed in Inelastic Data analysis where the first value would be ignored when a fit was performed.
Two bugs have been fixed in
ISISCalibration
in the Indirect Data Reduction interface. The first bug caused the resolution data to not be updated when the reflection was changed. The second bug sometimes caused a bad energy range selection for the resolution data.
Algorithms¶
New Features¶
IndirectILLReductionQENS and IndirectILLReductionFWS now offer the ability to switch off the detector grouping.
Added new workflow algorithm called SimpleShapeDiscusInelastic that calls DiscusMultipleScatteringCorrection with options for some simple shape types.
Bugfixes¶
The Abins algorithm has been reworked to account for q-dependence correctly when forming 3+ phonon events by self-convolution. This changes the results obtained when using the
Autoconvolution
option, which now results in the expected high-frequencywing
.

An error is fixed in Abins. This relates to the assignment of
Forward
andBackward
detector settings for TOSCA, which were reversed from their conventional definition. The default behaviour has not changed: results will only be affected for calculations which explicitly selected theForward (TOSCA)
orBackward (TOSCA)
options.A bug has been fixes in SofQWMoments that prevented it from working with OSIRIS data.
