Indirect Geometry Changes¶

Table of Contents

Improvements ¶

Instrument definition is improved for IN16B to have the physical detector on the correct side of the beam axis, and different analyser focus for single detectors.
Able to choose a list of spectra for plotting for all Indirect Interfaces. For example, under Data Analysis>Elwin, entering 0-2,4,6-8 and clicking Plot Spectra will plot the workspace indices 0, 1, 2, 4, 6, 7 and 8. The same can be done for Plot Tiled on the Iqt tab. It is also possible to produce a contour plot using Plot Contour on the Diffraction Interface.
Intial parameters now estimated when user adds an expononential function in I(Q,t) Fit.
The Plotting Options have also been made more consistent across the interface.

IndirectQuickRun and IndirectSampleChanger have been extended to allow them to perform a Width Fit. This utilizes the new algorithm IndirectTwoPeakFit.
LoadILLIndirect is extended to support also the configurations with the first tube angle at 33.1 degrees.
IndirectILLEnergyTransfer now offers the possibility to enable or disable the detector grouping both for Doppler and BATS modes. By default the pixels will be grouped tube by tube as before.
IndirectILLEnergyTransfer offers an option to discard the single detectors if they were not enabled in the measurement.
SofQWNormalisedPolygon now checks input properties are valid.
IndirectILLReductionFWS will now integrate the inelastic peaks correctly, based on the peak positions in the monitor spectrum.

Improved the format of Abins HDF5 files to include readable set of advanced parameters. Values in the AbinsParameters module have been re-organised into a logical heirarchy; user scripts may need to be modified to match this.

A bug has been fixed in MatchPeaks which was causing wrong alignment in IndirectILLReductionQENS with unmirror option 7, when the peaks in the alignment run are too narrow to be fitted.
Fixed a bug where mantid could crash when using the S(Q,w) tab with a workspace created by the Energy Transfer Tab.
