Direct Geometry Changes¶

Algorithms ¶

The default value of monitor peak width multiplier (MonitorPeakWidthInSigmas) has been changed from 3 to 7 in DirectILLCollectData .

DirectILLReduction is fixed to handle the AbsoluteUnitsNormalisation option.
Updated instrument created by LoadNXSPE is now viewable in instrument 3D view.
LoadNXSPE now creates workspaces with the correct detector sizes, which was previously causing aliasing issues in SofQWNormalisedPolygon for small q-bin sizes.

The PyChop GUI now has the ability to handle multiple independently phased choppers.

The Crystal Field Python interface has two new fitting functions, two_step_fit and two_step_fit_sc, alternating optimization over field parameters and peak parameters. One function is based on the Mantid fitting for both parts, the other uses scipy.optimize.minimize for the field parameters.

Enabled the Cut algorithm to work with an Integration method for PSD type workspaces.

Fixed a bug that caused empty plot windows and crashes when running scripts generated from plot windows.
Fixed bug that prevented the print button from opening the print dialog.
Fixed bug that caused duplicated colour bars for slice plots and exceptions for cut plots when running a generated script while the original plot is still open.
Fixed bug in script generation for cut plots.
Cleaned up File menu for interactive cut plots.
Enabled editing for Bragg peaks on cut plots.
Prevented an exception when generating script from plot created via script.
Added legends for recoil lines and Bragg peaks on slice plots.
Fixed a bug that caused exceptions when scaling a workspace.
Added an error message when attempting to load a file by path on the data loading tab.
Fixed a bug that caused infinitely repeating energy unit conversions when changing the default energy unit.
When closing the dialog for adding a Bragg peak from a CIF file without selecting a CIF file, the corresponding menu entry now remains unselected.
Updated the misleading cut algorithm names and made a selection of cut algorithms available on cut tab.
Fixed Save to Workspace button on cut tabs and renamed it to Save to Workbench to avoid confusion.
Prevented non-Mslice plots to be displayed as an MSlice plot, as most buttons and menu items do not work in this case.
Added a check for the deprecated hold feature in pyplot.py.
