MuSR Changes

Interface

Improvements

  • Added a cancel button to the MaxEnt widget in Frequency Domain Analysis.
  • Added checkboxes for “add all pairs” and “add all groups” to the settings tab.
  • The data plot style in the settings tab of Muon Analysis, only alters the plot range. It no longer crops the data.
  • Results table in Muon Analysis now sets relevant columns to numeric.
  • The period display no longer becomes blank when changing the period selection in multiple fitting mode.
  • The group/pair selection in Muon Analysis no longer resets when changing tabs or loading data.
  • The Frequency Domain Analysis GUI now uses CalMuonDetectorPhases to create the phase table for PhaseQuad FFTs.
  • The Frequency Domain Analysis GUI now uses MuonMaxent to calculate the frequency spectrum in MaxEnt mode.
  • The ALC interface now allows background sections with negative values.
  • If data is loaded with 0 good frames into Muon Analysis then it will try to load the data without dead time correction (does not need number of good frames).
  • Muon analysis no longer disables the “co add” and “simultaneous” buttons in the multiple fitting interface.
  • Frequency domain analysis will reload the data if the active workspace has changed.
  • Muon analysis no longer crashes when using the browse button in sequential fitting.
  • The period summation/subtraction can now be used in multiple fitting.
  • Muon analysis now handles the “auto background” gracefully in single and multiple fitting modes.
  • We have disabled some non functional graph right click context menu items or adding functions when in multi data fitting mode, in the Data Analysis tab of the Muon Analysis Interface.
  • Frequency domain analysis will produce a warning if there is no data to load.

Bug fixes

  • Log values are no longer filtered by start time when loaded into muon analysis.

Algorithms

New

  • MuonMaxent calculates a single frequency spectrum from multiple time domain spectra.

Improvements

  • MuonProcess now has a flag to determine if to crop the input workspace (default is true). In the Muon Analysis interface this flag has been set to false.
  • EstimateMuonAsymmetryFromCounts: if the number of good frames is zero, then a value of 1 is assumed for the number of good frames.

Bug fixes

  • CalMuonDetectorPhases has had the sign of the phase shift changed, this produces data with a positive frequency spike as expected.
