    • TFMuonium

    • ZFdipole

    • ZFelectronDipole

    • ZFMuonium

    • ZFprotonDipole

Improvements

• The speed of plotting during Sequential Fits.

• Removed the creation of a group of groups from the Elemental Analysis GUI. It will now create a workspace for each detector, with each workspace containing three spectra corresponding to Total, Delayed and Prompt data.

• Muon Analysis Interface>Fitting>Property>TF Asymmetry mode now rescales the fit to match the rescaled data.

• Adding a pair by right clicking now allows a name to be specified.

• The ALC interface can now safely be closed while loading a set of runs. On an initial close request the algoirthm will be cancelled. The window then be closed.

Algorithms

• Improve the handling of LoadPSIMuonBin where a poor date is provided.

• LoadPSIMuonBin has been improved to correctly load data other than data from Dolly at the SmuS/PSI.

• When there is a T0 for each spectrum, LoadPSIMuonBin chooses the max value out of the array instead of the first value.

Muon Analysis 2 and Frequency Domain Interfaces

• When loading PSI data if the groups given are poorly stored in the file, it should now produce unique names in the grouping tab for groups.

• When switching between Data Sets, Groups selected to fit are remembered.

• The Frequency Domain>Transform>FFT tab now uses Group Pair Selection to guess at the User’s selection for workspaces.

• Can now plot FFT’s of PhaseQuad data.

• Both interfaces work with Project Recovery.

• The original Muon Analysis GUI has been renamed “Muon Analysis Old” and has been deprecated.

• * The new Muon Analysis GUI has been renamed Muon Analysis. *

Bug Fixes

• No longer produces an error if using multiple runs and the user plots all the FFT results when no imaginary data was used.

• Fixed an issue where changing the normalisation on a plot with auto-scale disabled throws an exception.

• Fixed an issue where warnings about adding workspaces to workspace groups multiple times were appearing in the log.

• Fixed an issue where logs in TF asymmetry mode were not being propogated to the results tab.

• Fixed an issue where Muon Analysis 2 would crash if a polynomial background was used in combination with another fitting function.

• Fixed an issue where changing the dead time to from table workspace or other file did not work and reverted back to from data file.

• Fixed an issue where the Auto button in the ALC interface would crash mantid if it failed to find a list of valid of files. It will now show an error if it fails to find a set of files.
